As mentioned in a different sub-thread this cannot be built as a
module so I updated the commit message to:

imx: Fix typo

A one character difference in the name supplied to MODULE_DEVICE_TABLE
breaks compilation for SOC_IMX8M after built-in modules can generate
match-id based module aliases, so fix the typo.

This was not caught earlier because SOC_IMX8M can not be built as a
module and MODULE_DEVICE_TABLE is a no-op for built-in modules.

Fixes: 556f5cf9568a ("soc: imx: add i.MX8MP HSIO blk-ctrl")
