In mv_platform_probe(), check the return value of clk_prepare_enable()
and return the error code if clk_prepare_enable() returns an
unexpected value.

Nit:
Instead of:
ata: sata_mv: aspeed: fix value check in mv_platform_probe()
something like:
ata: sata_mv: aspeed: check clk_prepare_enable() return code
Might be slightly more descriptive.
Will leave it up to the maintainer though.
Kind regards,
Niklas
