[PATCH] ARM: OMAP4: Fix definition of IS_PM44XX_ERRATUM

[Nishanth Menon]

Just like IS_PM34XX_ERRATUM, IS_PM44XX_ERRATUM is valid only if
CONFIG_PM is enabled, else, disabling CONFIG_PM results in build
failure complaining about the following:
arch/arm/mach-omap2/built-in.o: In function `omap4_boot_secondary':
:(.text+0x8a70): undefined reference to `pm44xx_errata'

Fixes: c962184 (ARM: OMAP4: PM: add errata support)

Patch based on: v3.14-rc6
