[PATCH AUTOSEL for 4.9 074/190] gpio: gpio-wcove: fix irq pending status bit width

[Sasha Levin]

From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppusw...@linux.intel.com>

[ Upstream commit 7c2d176fe3f8dce632b948f79c7e89916ffe2c70 ]

Whiskey cove PMIC has three GPIO banks with total number of 13 GPIO
pins. But when checking for the pending status, for_each_set_bit() uses
bit width of 7 and hence it only checks the status for first 7 GPIO pins
missing to check/clear the status of rest of the GPIO pins. This patch
fixes this issue.
