In my tests terminating a transaction took about 25ms, what is
in line with the chip-internal timeout as described in 5.21.3.2
"Bus Time Out" in [0]. Therefore the 2ms delay is too low.
Instead of a fixed delay let's use i801_wait_intr() here,
this also facilitates the status handling.
This potential issue seems to have been existing forever, but as no
related problem is known, treat it as an improvement.

Clock handling can be very simplified with using devm_clk_get_enabled() as
was done by commit 8d2aaf4382 ("gpio: zynq: Simplify using
devm_clk_get_enabled()").
And also fix issue in connection to incorrect sequence when err_clk_dis
label is called.
When reset_control_deassert() fails it jumps to err_clk_dis label which
disables clock and also disable pm_runtime setup but nothing has been setup
at this time of failure because initialization is done below
reset_control_deassert() call.

When the I2C QUP controller is used together with a DMA engine it needs
to vote for the interconnect path to the DRAM. Otherwise it may be
unable to access the memory quickly enough.
The requested peak bandwidth is dependent on the I2C core clock.
To avoid sending votes too often the bandwidth is always requested when
a DMA transfer starts, but dropped only on runtime suspend. Runtime
suspend should only happen if no transfer is active. After resumption we
can defer the next vote until the first DMA transfer actually happens.
The implementation is largely identical to the one introduced for
spi-qup in commit ecdaa94730 ("spi: qup: Vote for interconnect
bandwidth to DRAM") since both drivers represent the same hardware
block.

Similar to qcom,geni-i2c, for i2c-qup we need to vote for performance
states on the VDDCX power domain to ensure that required clock rates
can be generated correctly.
I2C is typically used with a fixed clock rate, so a single required-opp
is sufficient without a full OPP table (unlike spi-qup for example).

Refactor the current implementation of the high-level composite read and
write operations in preparation of the addition of block-mode read/write
operations.
The sending of the i2c command is generic and will apply for both the
block-mode and non-block-mode ops. Extract this from the current hlc
ops, and place into a generic function, octeon_i2c_hlc_cmd_send.
The considerations made for extended addresses in the command
construction are almost common for all cases, extract these into
octeon_i2c_hlc_ext. There is one difference between the extended read
and write cases. When performing extended read or writes the SW_TWSI_EXT
must be written with an extended internal address, but the data field is
only filled in the write case (read back in read case). This results in
the original code block for the read case immediately writing this
register, while the write case fills in any data and then writes the
register. To create a common block of code for both processes remove the
SW_TWSI_EXT write from within the code block and instead in it's place a
variable is set, set_ext, which is returned and used as a condition to
do the register write, in the read command case.
There are parts of the commands construction which are common (only in
the read case), extract this and place into generic function
octeon_i2c_hlc_read_cmd. This function also reads the return from
octeon_i2c_hlc_ext and completes the write to SW_TWSI_EXT if required.
The write commands cannot be made entirely into common code as there are
distinct differences in the block mode and non-block-mode process.
Particularly the writing of data into the buffer.

Currently, it seems like the code was carried over from RDNA3 because
it assumes two possible values to set. RDNA4, instead of having:
0: min SCLK
1: max SCLK
only has
0: SCLK offset
This change makes it so it only reports current offset value instead of
showing possible min/max values and their indices. Moreover, it now only
accepts the offset as a value, without the indice index.
Additionally, the lower bound was printed as %u by mistake.
