clk: en7523: Fix wrong BUS clock for EN7581

The Documentation for EN7581 had a typo and still referenced the EN7523
BUS base source frequency. This was in conflict with a different page in
the Documentration that state that the BUS runs at 300MHz (600MHz source
with divisor set to 2) and the actual watchdog that tick at half the BUS
clock (150MHz). This was verified with the watchdog by timing the
seconds that the system takes to reboot (due too watchdog) and by
operating on different values of the BUS divisor.

The correct values for source of BUS clock are 600MHz and 540MHz.

This was also confirmed by Airoha.
