[PATCH] ram: aspeed: Use dev_read_addr_x() API

[peng.fan at nxp.com]

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

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

While at here, also use ofnode_read_s32_default() to replace
fdtdec_get_int().

No functional changes.
