drivers: gpio: add support for RA8P1

RA8P1 has 14 ports (from 0 to d) and 32 external irq while current
driver support 12 ports (0 to b) and 16 external irq.
This add addtional support for remain ports and external irq to be
able to work with RA8P1.

Fix the lack condition GPIO_RA_IOPORT for GPIO_RA_HAS_VBTICTLR
