Subject: [PATCH v3 2/3] ata: ahci: Rename `AHCI_HFLAG_IS_MOBILE`

`AHCI_HFLAG_IS_MOBILE` designates that a chipset should be using the
default link power management policy from a kernel configuration item.

As desktop chipsets may also be interested in this default policy
configuration, rename the flag to `AHCI_HFLAG_USE_LPM_POLICY` to more
accurately reflect that a chipset doesn't have to be mobile to adopt it.
