Bluetooth: btintel: Set Per Platform Antenna Gain(PPAG)

Antenna gain is defined as the antenna’s ability to
increase the Tx power in a given direction. Intel
is certifying its products with fixed reference
antenna peak gain values (3/5dBi). The feature takes
into account the actual antenna gain, and increases
output power values, which results in a performance
improvement.

After firmware download is completed, driver reads from
ACPI table and configures PPAG as required. ACPI table
entry for PPAG is defined as below.

Name (PPAG, Package (0x02)
{
    0x00000001,
    Package (0x02)
    {
        0x00000012, /* Bluetooth Domain */
        0x00000001  /* 1 - Enable PPAG, 0 - Disable PPAG */
    }
})
