[PATCH v3 5/5] remoteproc: switch drivers to optional resource-table helper

[Ben Levinsky <ben.levinsky@amd.com>]

Use the shared optional resource-table helper in the remoteproc drivers
that already treat a missing resource table as non-fatal:
xlnx_r5_remoteproc, rcar_rproc, stm32_rproc, imx_rproc, and
imx_dsp_rproc.

Keep thin local parse_fw() wrappers in each driver so the helper only
centralizes the return-value handling while each platform retains
control over whether the missing-table case is logged and at
what severity.
