Earlier the PREEMPT_RT patch had a PREEMPT_RT_FULL and PREEMPT_RT_BASE
Kconfig option. The latter was a subset the functionality that was
enabled with PREEMPT_RT_FULL and was mainly useful for debugging.
During the merging efforts the two Kconfig options were abandoned in the
v5.4.3-rt1 release and since then there is only PREEMPT_RT which enables
the full features set (as PREEMPT_RT_FULL did in earlier releases).
Replace the PREEMPT_RT_FULL reference with PREEMPT_RT.
