create a wrapper ceva_ahci_platform_enable_resources() API -> introduce the

What is "It" ?

Same here, but may be "It" == "this commit" ?
If that is the case, then simply rewrite your sentences simply like:

ceva_ahci_platform_enable_resources() is also used in the resume path
as the same SATA programming sequence (as in probe) should be followed.
Also cleanup the mixed usage of ahci_platform_enable_resources() and custom
implementation in the probe function as both are not required.
