arm: tegra: ahci/sata: Add SATA driver
Upgrade the Tegra 3 SATA driver to support kernel 3.1.
The driver supports runtime_pm when doing power-gating during idle.
A new CONFIG_TEGRA_SATA_IDLE_POWERGATE is provided to enable/disable
power-gating during idle.
When sata clocks (sata, sata-oob and pll_e clocks) are in the
core_dvfs_table[] table, CONFIG_TEGRA_SATA_IDLE_POWERGATE must not
be enabled.
Currently, sata clocks are in the core_dvfs_table[]. Those clocks
will not be in that table in the future. By then,
CONFIG_TEGRA_SATA_IDLE_POWERGATE can then be enabled.
