Subject: [PATCH 5.10 428/717] watchdog: armada_37xx: Add missing dependency on HAS_IOMEM

From: Guenter Roeck <linux@...ck-us.net>

[ Upstream commit 7f6f1dfb2dcbe5d2bfa213f2df5d74c147cd5954 ]

The following kbuild warning is seen on a system without HAS_IOMEM.

WARNING: unmet direct dependencies detected for MFD_SYSCON
  Depends on [n]: HAS_IOMEM [=n]
  Selected by [y]:
  - ARMADA_37XX_WATCHDOG [=y] && WATCHDOG [=y] && (ARCH_MVEBU || COMPILE_TEST

This results in a subsequent compile error.

drivers/watchdog/armada_37xx_wdt.o: in function `armada_37xx_wdt_probe':
armada_37xx_wdt.c:(.text+0xdc): undefined reference to `devm_ioremap'

Add the missing dependency.
