serial: liteuart: relax compile-test dependencies

Browse Source 
The LITEX symbol is neither a build or runtime dependency for the
liteuart serial driver.

LITEX is selected by the "LiteX SoC Controller" driver, which does a
probe-time register-access sanity check and panics if the SoC has not
been configured correctly. That driver's Kconfig entry asserts that any
LiteX driver using the LiteX register accessors should depend on LITEX,
but currently only the serial driver complies.

Relax this LITEX "dependency" in order to make it easier to compile test
the driver.
