soc/intel/cannonlake: Configure GPIO PM configuration in bootblock

This patch performs below operations:
1. Rename soc_fill_gpio_pm_configuration to soc_gpio_pm_configuration
2. Move soc_gpio_pm_configuration() to gpio_common.c
3. Calling from bootblock and after FSP-S to ensure GPIO PM configuration
is updated with devicetree.cb value even with platform reset.

BUG=b:144002424
TEST=coreboot configures all MISCCFG.bit 0-5 local clock gating based on devicetree.cb
