Subject: [PATCH] mmc: dw_mmc: make irq flags 'unsigned long'

The newly added spin_lock_irqsave() passes an argument of the
wrong type, leading to a warning about non-portable code:

drivers/mmc/host/dw_mmc.c: In function 'dw_mci_set_drto':
include/linux/typecheck.h:11:18: error: comparison of distinct pointer types lacks a cast [-Werror]
  (void)(&__dummy == &__dummy2); \
drivers/mmc/host/dw_mmc.c:1953:2: note: in expansion of macro 'spin_lock_irqsave'
  spin_lock_irqsave(&host->irq_lock, irqflags);

This changes the type to 'unsigned long' as it should be.

Fixes: 80a2a5a7745b ("mmc: dw_mmc: Cleanup the DTO timer like the CTO one")
