[PATCH v2 10/23] powerpc/optprobes: Remove unused routine patch_imm32_load_insns()

[Cédric Le Goater]

Commit 650b55b707fd ("powerpc: Add prefixed instructions to instruction
data type") removed the use of patch_imm32_load_insns(). Clean it up
to fix this W=1 compile error :

../arch/powerpc/kernel/optprobes.c:149:6: error: no previous prototype for ‘patch_imm32_load_insns’ [-Werror=missing-prototypes]
  149 | void patch_imm32_load_insns(unsigned int val, kprobe_opcode_t *addr)
