watchdog: rti: Use dev_read_addr_ptr()
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.
