gpio: davinci: Clear interrupt status in every bank on suspend

Browse Source 
davinci_gpio_save_context() saves the registers of each 32-GPIO
register bank, but clears interrupt status only after the loop. At that
point g refers to the last bank, so pending status in all preceding
banks is left uncleared.

Move the interrupt-status write into the per-bank loop so that the
existing suspend-time clearing covers every register bank. Single-bank
controllers retain the same behavior.
