bdda257cd3 i3c: master: cdns: Update maximum prescaler value for i2c clock 
[ Upstream commit 374c13f9080a1b9835a5ed3e7bea93cf8e2dc262 ]

As per the Cadence IP document fixed the I2C clock divider value limit from
16 bits instead of 10 bits. Without this change setting up the I2C clock to
low frequencies will not work as the prescaler value might be greater than
10 bit number.

I3C clock divider value is 10 bits only. Updating the macro names for both.

IBIR_DEPTH and CMDR_DEPTH should read from status0 instead of status1.
