Subject: [PATCH 5.15 45/72] gpio: gpio-aspeed-sgpio: Fix wrong hwirq base in irq handler

From: Steven Lee <steven_lee@...eedtech.com>

commit e5a7431f5a2d6dcff7d516ee9d178a3254b17b87 upstream.

Each aspeed sgpio bank has 64 gpio pins(32 input pins and 32 output pins).
The hwirq base for each sgpio bank should be multiples of 64 rather than
multiples of 32.
