MIPS: Fix incomplete separation of XPA CPU feature
Commit 12822570a29b ("MIPS: Separate XPA CPU feature into LPA and MVH") wasn't fully applied, possibly due to a conflict with commit f270d881fa55 ("MIPS: Detect MIPSr6 Virtual Processor support"). This left decode_config5() referring to the non-existent MIPS_CPU_XPA, which breaks the build when XPA is enabled: arch/mips/kernel/cpu-probe.c In function ‘decode_config5’: arch/mips/kernel/cpu-probe.c:838:17: error: ‘MIPS_CPU_XPA’ undeclared (first use in this function) c->options |= MIPS_CPU_XPA; ^ Apply the missing hunk, dropping the CONFIG_XPA ifdef and setting the MIPS_CPU_MVH option when Config5.MVH is set.
