Subject: [PATCH 1/4] ARM: OMAP2+: omap_hwmod: provide space for more hwmod flags

From: Sekhar Nori <nsekhar@...com>

'flags' member of omap_hwmod structure is fast running
out of space with 16 different flags already defined.

Make flags a 32-bit entity so as to allow for more flags.

This results is a ~2.3K data section size increase with
TI config fragments.

before:
   text	   data	    bss	    dec	    hex	filename
8886648	 610452	 261876	9758976	 94e900	vmlinux

after:
   text	   data	    bss	    dec	    hex	filename
8886584	 612820	 261876	9761280	 94f200	vmlinux
