[PATCH 5.5 112/367] nvmem: imx: scu: fix write SIP

[Greg Kroah-Hartman]

From: Peng Fan <peng.fan@xxxxxxx>

commit 40bb95dbb8acca35f8d52a833393ddbb01cfa2db upstream.

SIP number 0xC200000A is for reading, 0xC200000B is for writing.
And the following two args for write are word index, data to write.

Fixes: 885ce72a09d0 ("nvmem: imx: scu: support write")
