[PATCH] ARM: tegra: fix section mismatch in tegra_pmc_parse_dt

[Stephen Warren]

From: Stephen Warren <swarren-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

tegra_pmc_parse_dt() references __initconst data. Fix it to be __init.
This matches its only usage; a call from tegra_pmc_init() which is
already __init. This fixes:

WARNING: vmlinux.o(.text.unlikely+0x580): Section mismatch in reference
from the function tegra_pmc_parse_dt() to the (unknown reference)
.init.rodata:(unknown)

Hi Stephen,

Just curious, I don't see this warning message on my system. Does this
cause by some other patch or something else?

Thanks,
Joseph

The warning only shows up with CONFIG_DEBUG_SECTION_MISMATCH=y, which
isn't in tegra_defconfig.
