ARM: tegra: avoid section mismatch warning

WARNING: vmlinux.o(.text+0x39ecc): Section mismatch in reference from the function tegra114_gic_cpu_pm_registration() to the (unknown reference) .init.rodata:(unknown)
The function tegra114_gic_cpu_pm_registration() references
the (unknown reference) __initconst (unknown).
This is often because tegra114_gic_cpu_pm_registration lacks a __initconst
annotation or the annotation of (unknown) is wrong.
