Subject: [PATCH] serial: clps711x: Enable driver compilation with COMPILE_TEST

This helps increasing build testing coverage.
To do this, read{write}_relaxed() functions was be replaced with
simple read{write}() variants. Potential "uninitialized variable"
warnings was be fixed if driver compiled without MFD_SYSCON.
