pinctrl: sprd: Combine the condition of MISC_PIN and COMMON_PIN
Since the follow-up pin design on Spreadtrum platform has some changes,
some configuration of MISC_PIN moved to COMMON_PIN. To support current
pin design and keep backward compatibility, we should combine the
condition of MISC_PIN and COMMON_PIN to configure an individual pin.
