Move probe out of __init section and don't use platform_driver_probe
which cannot be used with deferred probing.
Since commit e9354576 ("gpiolib: Defer failed gpio requests by default")
this driver might return -EPROBE_DEFER if a gpio_request fails.

The nice thing about devm_* is that the driver doesn't need to free the
resources but the driver core takes care about that. This also
simplifies the error path quite a bit and removes the wrong check for a
clock pointer being NULL.

Add pitch length info of graphics/video layer, pitch is used
to represent line length in byte, the usage depends on pix_fmt.
If the fmt is YUV, the pitch[0] will be Y length,pitch[1]
will be U length, pitch[2] will be V lenth.
If the fmt is RGB, the picth[0] will be line lenth, and
pitch[1]/pitch[2] will be 0 and not be used.

We could set rb swap in two modules: DMA controler input part and
dsi interface output part.
DMA input part is based on pix_fmt to set rbswap, dsi output interface
part will set rbswap based on platform dsi_rbswap configuration.
This patch include below change and enhancement:
1) The input format which support rbswap is based on RGB format,
eg. RGB565 indicates the source data in memory is that Red is [15~11],
Green is [10~5], Blue is [4:0], Red is MSB, Blue is LSB, but for the
display dma input default setting(rbswap = 0), it only support Blue
is [15~11], Green is [10~5], Red is [4:0], Red is LSB, Blue is MSB,
so for this format(RGB565), display controller need to set rbswap
= 1 and it can support the MSB/LSB correctly.
BGR/YUV format will not set it in mmp display driver.
2) The dsi output part of rbswap is depend on dsi_rbswap which is
defined in specific platfrom. For output dsi interface, it has this
feature to do rbswap again if it needs specifc byte sequence of RGB
byte for DSI panel.
eg. If display content is set RGB565 in memory and DMA input part set
rbswap in driver to support Red as MSB , Blue LSB, but dsi panel only
support Red as LSB, Blue as MSB, then it can use this feature.
If there is no this requirement of panel, this dsi output part is not
needed.
