The production tester breaks with DMA disabled, so enable it again. Any breakage due to this should get reported to TI PSP so they can fix it.
This effectively reverts aa209df889

This trades "not working" for "slightly less performance" for a lot of use cases

First 3 patches are cherry picks from PSP.
Next 7 add support for gen purpose adc, MFD support, sysfs triggering etc.
Currently:
cat /sys/bus/platform/tsc/ain* will trigger sampling
Output of the 12-bit ADC will be in decimal 0-4095
TODO:
1. IIO driver support
2. Other ADC features

After processing one DMA completion, checking if rescheduling is
required instead of scheduling another completion request if the
FIFO is non empty.
This fixes high CPU load issue seen with g_mass_storage on a beaglebone
and could potentially fix similar issues seen with other gadget drivers
