According to the vendor driver v2.6.0.1, during the rf register init the SRAM
voltage should be increased to 1.35V and after 1ms decreased back to 1.2V. This
patch adds the field setting of LDO_CFG0_LDO_CORE_VLEVEL accordingly.

Hello,
I don't have the hardware to test, just stumbled over this while hacking on the
