sb/amd/pi/hudson: drop HUDSON_UART option and corresponding code

This option is neither selected nor usable for the only remaining SoC
that uses this code, so drop the remaining parts. configure_hudson_uart
isn't called anywhere and isn't even compiled, since it's guarded by an
#if CONFIG(HUDSON_UART) block and the HUDSON_UART Kconfig option isn't
selected anywhere. Both the offsets used in the iomux_write8 calls and
the UART controller itself aren't listed in the BKDG #52740 Rev 3.05 for
the AMD Family 16h Models 30h-3Fh APUs which is the only SoC that uses
this code, so the code didn't even apply for this chip.

TEST=Timeless build for pcengines/apu2 results in identical binary.
