ata: ahci_ceva: fix error handling for Xilinx GT PHY support



[ Upstream commit 26c8404e ]

Platform clock and phy error resources are not cleaned up in Xilinx GT PHY
error path.

To fix introduce the function ceva_ahci_platform_enable_resources() which
is a customized version of ahci_platform_enable_resources() and inline with
SATA IP programming sequence it does:

- Assert SATA reset
- Program PS GTR phy
- Bring SATA by de-asserting the reset
- Wait for GT lane PLL to be locked

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.
