[PATCH 2/3] watchdog: rti: Use dev_read_addr_ptr()

[Peng Fan (OSS)]

From: Peng Fan <peng.fan at nxp.com>

devfdt_get_addr() returns FDT_ADDR_T_NONE(-1UL) when fail, using
"!priv->regs" to check return value is wrong.

Replace devfdt_read_addr() with dev_read_addr_ptr() when retrieving the
register base address.

dev_read_addr_ptr() supports both live device tree and flat DT backends,
avoiding direct dependency on devfdt_* helpers.

Also use "void __iomem *" to replace "phys_addr_t" to avoid type
casting.

No functional changes.
