ASoC: sn95031: intel_sst: Fixes delay in powering up PLL and firmware download

Powering up of Audio rail and firmware download together was consuming 80ms
which didn't meet the latency requirement for openning a pcm device.

This patch fixes the delay during firmware download by caching the firmware
instead of using request_firmware() when firmware download is required and also
reduces the delay from 10ms to 1ms to power up PLL.
