[PATCH 1/2] ata: mtk_ahci: Use dev_remap_addr_index() and ofnode API

[peng.fan at nxp.com]

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

Use dev_remap_addr_index() instead of devfdt_remap_addr_index() to map the
controller registers, removing the dependency on FDT-specific helpers.

Replace the direct fdt_get_property() lookup combined with dev_of_offset()
by dev_read_prop().

No functional changes.
