Add support for the reset controller that's used on the i.MX7D and i.MX8MQ. This will be needed to be able to assert the PCIe reset pins. Bindings taken from Linux, driver implementation mostly taken from Linux and adjusted to U-Boot infrastructure.

help
|
|
Enable support for the reset controller driver class. Many hardware
|
|
modules are equipped with a reset signal, typically driven by some
|
|
reset controller hardware module within the chip. In U-Boot, reset
|
|
controller drivers allow control over these reset signals. In some
|
|
cases this API is applicable to chips outside the CPU as well,
|
|
although driving such reset isgnals using GPIOs may be more
|
|
appropriate in this case.
