[ Upstream commit 1132e90840abf3e7db11f1d28199e9fbc0b0e69e ]
The COREPLL_PWRDN bit in the BLCG register must be set when the XUSB
device controller is powergated and cleared when it is unpowergated.
If this bit is not explicitly controlled, the core PLL may remain in an
incorrect power state across suspend/resume or ELPG transitions.
Therefore, update the driver to explicitly control this bit during
powergate transitions.
