   3Mbps, so the bluetooth.

   It fixes issue

2. Move iomcu initialization from fastboot to xloader
   This patch delete iomcu initializtion in fastboot, and move iomcu subsys
   initializtion to xloader. Modules impacted by this including uart3, spi2,
   i2c0, i2c2.

   With iomcu initialization in xloader, there is no need to do this in UEFI.
   Thus save some effort.

   This patch also fix the bug of SPI2 not initialized correctly. See:
