The tx flow worker in msgbuf gets scheduled at tx till a certain
threshold has been reached. Then the tx completes will take over
the scheduling. When amsdu and ampdu is used the frames are
transferred wireless in a very bulky fashion, in combination
with this scheduling algorithm and buffer limiters in the stack
this can result in limited throughput. This change causes the
flow worker to be scheduled more frequently from tx.

Several of these drivers have there TX randomly blocked for 3~5 seconds while
measuring tx throughput (iperf). The root couse happens in rtl_pci_flush().
The function uses a while-loop to wait for TX queue length to decrease to 0.
The TX queue length counts the number of packets that are queued in the driver.
The driver relys on the TX OK interrupt to return skb and reduce TX queue length.
The interrupt subroutine disables interupts, reads the interrupt registers, and
then clears the registers in the beginning of _rtl_pci_interrupt(). After all
interupts process are finished, the driver invokes enable_interrupt() to enable
interupts. This behavior is normal for an interrupt subroutine.
But enable_interrupt() invokes clear_interrupt() again. This unexpected interrupt
clearing may cleari me fresh TX OK interrupts. These missing interrupts cause TX
queue length to never reduce to 0i, which causes rtl_pci_flush() to be stuck in
unterminated while-loop.
This patch removes clear_interrupt() in enable_interrupt() to avoid this behavior.

The PCI cache line size value was being compared against decimal values
prefixed with 0x.
Fixed the literals to use the correct hex values.
This has not been tested due to lack of hardware. However, the value in
`cline` is PCI cache line size, which is the CPU's cache line size.
It is less likely for cache line sizes to be 22 or 50, and more likely for
them to be 16 or 32. Also, as far as I understand, cache line size is used for
things like aligning DMA requests with CPU cache line, which improve
performance but wouldn't break anything if the value doesn't match. In
this case, we will fall through to the default case which leaves `reg`
unchanged.

The commit df59fa7f4b "spi: orion: support armada extended baud
rates" was too optimistic for the maximum baud rate that the Armada
SoCs can support. According to the hardware datasheet the maximum
frequency supported by the Armada 370 SoC is tclk/4. But for the
Armada XP, Armada 38x and Armada 39x SoCs the limitation is 50MHz and
for the Armada 375 it is tclk/15.
Currently the armada-370-spi compatible is only used by the Armada 370
and the Armada XP device tree. On Armada 370, tclk cannot be higher
than 200MHz. In order to be able to handle both SoCs, we can take the
minimum of 50MHz and tclk/4.
A proper solution is adding a compatible string for each SoC, but it
can't be done as a fix for compatibility reason (we can't modify
device tree that have been already released) and it will be part of a
separate patch.
