The UART code for the A3K platform assumes that UART parent clock rate
is always 25 MHz. This is incorrect, because the xtal clock can also run
at 40 MHz (this is board specific).
The frequency of the xtal clock is determined by a value on a strapping
pin during SOC reset. The code to determine this frequency is already in
A3K's comphy driver.
Move the get_ref_clk() function from the comphy driver to a separate
file and use it for UART parent clock rate determination.

When configuring the UART_BAUD_REG register, the function
console_a3700_core_init() currently only changes the baud divisor field,
leaving other fields to their previous value.
This is incorrect, because the baud divisor is computed with the
assumption that the parent clock rate is 25 MHz, and since the other
fields in this register configure the parent clock, which could have
been changed by U-Boot or Linux.
Fix this function to also configure the other fields so that the UART
parent clock is selected to be the xtal clock.
For example without this change TF-A prints only
ERROR: a3700_system_off needs to be implemented
followed by garbage after plat_crash_console_init() is called.
After applying this change instead of garbage it also print crash info:

Morello exhibits the behavior similar to Juno wherein CNTBaseN.CNTFRQ
can be written but does not reflect the value of the CNTFRQ register
in CNTCTLBase frame. This doesn't follow ARM ARM in that the value
updated in CNTCTLBase.CNTFRQ is not reflected in CNTBaseN.CNTFRQ.
Hence enable the workaround (applied to Juno) for Morello that updates
the CNTFRQ register in the Non Secure CNTBaseN frame.

UART parent clock is by default the platform's xtal clock, which is
25 MHz.
The value defined in the driver, though, is 25.8048 MHz. This is a hack
for the suboptimal divisor calculation
Divisor = UART clock / (16 * baudrate)
which does not use rounding division, resulting in a suboptimal value
for divisor if the correct parent clock rate was used.
Change the code for divisor calculation to
Divisor = Round(UART clock / (16 * baudrate))
and change the parent clock rate value to 25 MHz.
The final UART divisor for default baudrate 115200 is not affected by
this change.
(Note that the parent clock rate should not be defined via a macro,
since the xtal clock can also be 40 MHz. This is outside of the scope of
this fix, though.)
