enable the GPMI NAND driver for i.MX8, i.MX8 use similar controller as
i.MX8M
- register definition for i.mx8
- DMA structure must be 32bit address

The UDMA-P is intended to perform similar (but significantly upgraded) functions
as the packet-oriented DMA used on previous SoC devices. The UDMA-P module
supports the transmission and reception of various packet types.
The UDMA-P also supports acting as both a UTC and UDMA-C for its internal
channels. Channels in the UDMA-P can be configured to be either Packet-Based or
Third-Party channels on a channel by channel basis.
The initial driver supports:
- MEM_TO_MEM (TR mode)
- DEV_TO_MEM (Packet mode)
- MEM_TO_DEV (Packet mode)

This adds channels support for dma controllers that have multiple channels
which can transfer data to/from different devices (enet, usb...).
DMA channle API:
dma_get_by_index()
dma_get_by_name()
dma_request()
dma_free()
dma_enable()
dma_disable()
dma_prepare_rcv_buf()
dma_receive()
dma_send()
