Ivan Grokhotkov 3b583c150f bootloader: disconnect VRTC from SAR input in bootloader_random_disable
Bootloader enables SAR ADC in test mode to get some entropy for the RNG.
The bits which control the ADC test mux were not disabled, which caused
extra ~24uA current to be drawn from VRTC, increasing deep sleep current
consumption. This change disables relevant test mode bits in
bootloader_random_disable.
