Subject: [PATCH] mmc: host: omap_hsmmc: constify dev_pm_ops structures.

dev_pm_ops are not supposed to change at runtime. All functions
working with dev_pm_ops provided by <linux/device.h> work with const
dev_pm_ops. So mark the non-const structs as const.

File size before:
text data bss dec hex filename
11586 624 0 12210 2fb2 drivers/mmc/host/omap_hsmmc.o

File size After adding 'const':
text data bss dec hex filename
11778 432 0 12210 2fb2 drivers/mmc/host/omap_hsmmc.o
