ata: ahci_ceva: Fix id array access in ceva_ahci_read_id()
ATA IDENTIFY command returns an array of le16 words. Accessing it as a
u16 array triggers the following sparse warning:
drivers/ata/ahci_ceva.c:107:33: warning: invalid assignment: &=
drivers/ata/ahci_ceva.c:107:33: left side has type unsigned short
drivers/ata/ahci_ceva.c:107:33: right side has type restricted __le16
Use a local variable to explicitly cast the id array to __le16 to avoid
this warning.
