EDAC/altera: Use the proper type for the IRQ status bits
[ Upstream commit 8faa1cf6ed82f33009f63986c3776cc48af1b7b2 ]
Smatch complains about the cast of a u32 pointer to unsigned long:
drivers/edac/altera_edac.c:1878 altr_edac_a10_irq_handler()
warn: passing casted pointer '&irq_status' to 'find_first_bit()'
This code wouldn't work on a 64 bit big endian system because it would
read past the end of &irq_status.
