Subject: [PATCH 1/3] ARM: at91: pm: fix .uhp_udp_mask specification for current SoCs

From: Nicolas Ferre <nicolas.ferre@...rochip.com>

All SoCs using this structure field .uhp_udp_mask in configuration
index 4 don't have the bit 7 specified: sam9x60 nor sam9x75.
Remove this bit from the mask definition to match register layout.

This mask is used in function at91_pm_verify_clocks().
