ata: Kconfig: Update SATA_MOBILE_LPM_POLICY default to med_power_with_dipm
Historically this was set to "keep_firmware_settings" to prevent problems with power management on very old drives. However it's been observed that almost all modern Linux distributions either set the policy to "med_power_with_dipm" in the kernel configuration or update it to this via userspace policy changes. Update the policy default in the kernel to "med_power_with_dipm" to match that behavior as well. Changing the default was previously not a good idea, because LPM disables detection of hot plug removals, however, since commit ae1f3db006b7 ("ata: ahci: do not enable LPM on external ports"), a port marked as external will always be initialized to "keep_firmware_settings", regardless of the SATA_MOBILE_LPM_POLICY Kconfig value. Therefore, changing the default is now considered safe (external ports included).
