serial: 8250_fintek: Enable high speed mode on Fintek F81866
Fintek F81866 supports baud rates higher than 115200 but needs to raise
it's clock speed from 1.84 to 14.76 MHz.
This is eight times faster, so gives 921600 as resulting baud_base.
F81866 clock register 0xf2:
Bit 7-2 reserved
Bit 1-0 00: 1.8432MHz
01: 18.432MHz
10: 24MHz
11: 14.769MHz
