[PATCH] target/ppc: Fix build warnings when building with 'disable-tcg'

[Vaibhav Jain]

Kowshik reported that building qemu with GCC 12.2.1 for 'ppc64-softmmu'
target is failing due to following build warnings:

<snip>
 ../target/ppc/cpu_init.c:7018:13: error: 'ppc_restore_state_to_opc' defined 
but not used [-Werror=unused-function]
 7018 | static void ppc_restore_state_to_opc(CPUState *cs,
<snip>

Fix this by wrapping these function definitions in 'ifdef CONFIG_TCG' so that
they are only defined if qemu is compiled with '--enable-tcg'
