powerpc: Fix HMIs on big-endian with CONFIG_RELOCATABLE=y
HMIs will crash the kernel due to
BRANCH_LINK_TO_FAR(hmi_exception_realmode)
Calling into the OPD instead of the actual code.
Fixes: 2337d207288f ("powerpc/64: CONFIG_RELOCATABLE support for hmi interrupts")

[mpe: Use DOTSYM() rather than #ifdef]
