CONFIG_MICROCODE_OLD_INTERFACE=y
with both
# CONFIG_MICROCODE_INTEL is not set
# CONFIG_MICROCODE_AMD is not set
off. Which makes building the microcode functionality a little
pointless. Don't do that in such cases then.

The thermal_release function is called whenever
any device belonging to 'thermal' class unregisters.
This function performs kfree(cdev) without any check.
In cases where there are more device registrations
other than just 'thermal_zone' and 'cooling_device'
this might accidently free memory allocated them
silently; and cause memory errors.
This patch changes this behavior by doing
kfree(cdev) only when the device pointer belongs
to a real cdev i.e. cooling_device.

Build AM43x power domain, clock domain and hwmod data.
Many of AM43x IP's and interconnects are similar as that in AM335x,
hence AM335x hwmod data is being reused with necessary changes.
Earlier the plan was to reuse AM335x specific PRCM code, but as AM43x
PRCM register layout is much similar to OMAP4/5, AM335x PRCM is
divorced and instead married with OMAP4/5 PRCM for AM43x.

Reuse OMAP4 operations on AM43x.
Context related ops are not used on AM43x, as this would not add value
when using DT and AM43x is DT only boot. This additionally helps not to
add context register offset for each hwmod.

Add hwmod support for IP's that are present in AM43x, but not in AM335x.
AM43x additional ones added here are,
1. synctimer
2. timer8-11
3. ehrpwm3-5
4. spi2-4
5. gpio4-5
AM43x pruss interconnect which is different as compared to AM335x, has
been taken care.
And register offsets for same hwmod's shared with AM335x is different,
AM43x register offsets are updated appropriately.
ocp clock of those in l4_wkup is fed from "sys_clkin_ck" instead of
"dpll_core_m4_div2_ck", so "ocpif" for those in AM43x l4_wkup has been
added seperately.
hwmod's has been added for those that have main clock (wkup_m3, control,
gpio0) and clock domain (l4_hs) different from AM335x. debugss and
adc_tsc that have different clocks and clockdomains repectively has not
been added due to the reasons mentioned below.
AM43x also has IP's like qspi, hdq1w, vpfe, des, rng, usb, dss, debugss,
adc_tsc. These are not handled here due to both/either of following
reasons,
1. To avoid churn; most of them don't have DT bindings, which would
necessitate adding address space in hwmod, which any way would have
to be removed once DT bindings happen with driver support.
2. patches would come in from sources other than the author

Most of IP's in AM335x is present on AM43x and so in those cases both
will use same hwmod database (except for a few cases where clock related
details differ), but there is difference w.r.t register offset between
these. Update register offsets at runtime based on the SoC detected to
help in sharing otherwise same hwmod.

AM335x and AM43x have most of the IP's and interconnect's similar.
Instead of adding redundant hwmod data, move interconnects and hwmod
similar between AM335x and AM43x to a common location. This helps in
reuse on AM43x.
AM335x interconnects that has difference and not present in AM43x are
not moved. ocp clock of those in l4_wkup is fed from a different source
for AM43x. Also pruss interconnect is different.
AM335x hwmod's that has difference other than prcm register offsets
(difference is in clocks of wkup_m3, control, gpio0, debugss and clock
domain of l4_hs, adc_tsc as compared to AM43x) and those that are not
present in AM43x are not moved.

Most of the AM43x CM reg address offsets are with MSB bit '1' (on
16-bit value) leading to arithmetic miscalculations while calculating
CLOCK ENABLE register's address because cm_inst field was a type of
"const s16", so make it "const u16".
Also modify relevant functions so as to take care of the above.
