wifi: rtw88: Handle RTL8723D(S) with blank efuse

Browse source

Some users have RTL8723DS chips with nearly blank efuse. Currently these
chips cannot connect when using rtw88, but they do work using the old
out-of-tree driver.

Use reasonable default values for TX power, antenna configuration, and
crystal cap if the chip's efuse is missing these things.

RTL8723D can use the same default values as RTL8703B, so simply move
the code from rtl8703b_read_efuse() to the shared function
__rtl8723x_read_efuse().
