[PATCH] soc: brcmstb: pm-arm: Remove duplicate/repeating constant

[Deepak R Varma]

Constant DDR_PHY_RST_N is unnecessarily or'ed with itself. Remove
the redundant constant from the expression.
Issue identified using doublebitand.cocci Coccinelle semantic patch.

Please note: I was unable to build the change though I had the appropriate
config, arch and  cross compiler. I used the following:
	.config = bmips_stb_defconfig
	ARCH=mips
	CROSS_COMPILE=/usr/bin/mips-linux-gnu-
	BRCMSTB_PM=y

Let me know what I missed so I can build the objects myself. Thank you.
