regmap-irq: Fix a bug in regmap_irq_enable() for type_in_mask chips

[ Upstream commit 485037ae9a095491beb7f893c909a76cc4f9d1e7 ]

When enabling a type_in_mask irq, the type_buf contents must be
AND'd with the mask of the IRQ we're enabling to avoid enabling
other IRQs by accident, which can happen if several type_in_mask
irqs share a mask register.

Fixes: bc998a730367 ("regmap: irq: handle HW using separate rising/falling edge interrupts")
