[PATCH 1/5] memory: renesas-rpc-if: Return correct value to the caller of rpcif_manual_xfer()

[Lad Prabhakar]

In the error path of rpcif_manual_xfer() the value of ret is overwritten
by value returned by reset_control_reset() function and thus returning
incorrect value to the caller.

This patch makes sure the correct value is returned to the caller of
rpcif_manual_xfer() by dropping the overwrite of ret in error path.
Also now we ignore the value returned by reset_control_reset() in the
error path and instead print a error message when it fails.

[PATCH 2/5] memory: renesas-rpc-if: Make rpcif_enable/disable_rpm() as static inline

[Lad Prabhakar]

Define rpcif_enable_rpm() and rpcif_disable_rpm() as static
inline in the header instead of exporting it.

Looking at how this is used, this should call pm_runtime_disable()
instead.

And probably this should be moved inside the core RPC-IF driver:
  1. pm_runtime_enable() could be called from rpcif_sw_init(),
  2. pm_runtime_put_sync() can be called from a new rpc_sw_deinit()
     function, to be called by the SPI and MTD drivers on probe failure
     and on remove.

   Ugh... sorry for this blunder (that went unnoticed till now). Mind fixing
it to pm_runtime_disable() (before this patch)?

   No connection between these 2 changes, so there should be 2 patches, not 1.
Also, I'd like to ask you that they're left intact (unless it causes problems
