The imx_soc_device_init functions tries to fetch the ocotp regmap in
order to soc serial number. If regmap fetch fails then a message is
printed but regmap_read is called anyway and the system crashes.
Failing to lookup ocotp regmap shouldn't be a fatal boot error so check
that the pointer is valid.
Only side-effect of ocotp lookup failure now is that serial number will
be reported as all-zeros which is acceptable.

Signed-off-by: Leonard Crestez <redacted>As this is a fix we want it in 5.5-rc, it should be generated against 5.5-rc1 rather than -next. I rebased it and applied, thanks.
