pinctrl: baytrail: Debounce register is one per community
Debounce value is set globally per community. Otherwise user will easily
get a kernel crash when they start using the feature:
BUG: unable to handle kernel paging request at ffffc900003be000
IP: byt_gpio_dbg_show+0xa9/0x430
Make it clear in byt_gpio_reg().
Note that this fix just prevents kernel to crash, but doesn't make any
difference to the existing logic. It means the last caller will win the
trade and debounce value will be configured accordingly. The actual
logic fix needs to be thought about and it's not as important as crash
fix. That's why the latter goes separately and right now.
