mmc: moxart: use platform helpers for resource and IRQ

Replace of_address_to_resource() and the following devm_ioremap_resource()
with a single devm_platform_get_and_ioremap_resource() call in
moxart_probe(). This requests the register region and maps it once, which
is equivalent to the previous devm_ioremap_resource() behavior, and drops
the now-redundant separate resource lookup.

Similarly replace irq_of_parse_and_map() with platform_get_irq(), which
returns a negative errno on failure (including -EPROBE_DEFER) instead of
0, and tighten the error check to irq < 0.

Both substitutions are equivalent for a DT-backed platform device. The
remaining OF usage (mmc_of_parse() and the of_device_id table) is covered
by already-included headers, so linux/of_address.h and linux/of_irq.h
are dropped.

No functional change; the MMC register window is requested and mapped
exactly once, so there is no overlapping region claim.

Built for ARM (allmodconfig + CONFIG_MMC_MOXART) with LLVM=1;
drivers/mmc/host/moxart-mmc.o compiles cleanly.
