use gpio_set_wakepin() to enable or disable wake pins
This uses gpio_set_wakepin() to setup the wake pins instead of writing
to the PINMUX EXITEN registers directly.
This patch reduces the flash usage by 248 bytes.
BUG=b:35587259
BRANCH=cr50
TEST=checked pinmux configuration hasn't changed on coral.
Checked firmware_Cr50DeviceState running good on coral.
