MT2701 DRM support

This is MT2701 DRM support PATCH v8, based on 4.8-rc1.
We add DSI interrupt control, transfer function for MIPI DSI panel support.
Most codes are the same, except some register changed.

For example:
 - DISP_OVL address offset changed, color format definition changed.
 - DISP_RDMA fifo size changed.
 - DISP_COLOR offset changed.
 - MIPI_TX setting changed.

We add a new component DDP_COMPONENT_BLS, and the connections are updated.
OVL -> RDMA -> COLOR -> BLS -> DSI
RDMA -> DPI
And we have shadow register support in MT2701.

We remove dts patch from the patch series, which depends on MT2701 CCF and scpsys.

Changes since v7:
- Remove redundant codes
- Move the definition of DDP_COMPONENT_BLS to patch of "drm/mediatek: update display module connections"
- Move _dsi_irq_wait_queue into platform driver data
- Move mtk_dsi_irq_data_clear() to patch of "drm/mediatek: add dsi interrupt control"
- Add more descriptions in the commit messages

Changes since v6:
- Change data type of irq_data to u32
- Rewrite mtk_dsi_host_transfer() for simplify
- Move some MIPI_TX config to patch of "drm/mediatek: add *driver_data for different hardware settings".
- Remove device tree from this patch series

Changes since v5:
- Remove DPI device tree and compatible string
- Use one wait queue to handle interrupt status
- Update the interrupt check flow and DSI_INT_ALL_BITS
- Use same function for host read/write command
- various fixes

Changes since v4:
- Add messages when timeout in mtk_disp_mutex_acquire()
- Add descriptions for DISP_REG_MUTEX registers
- Move connection settings for display modules to a separate patch
- Remove 'mt2701-disp-wdma' because it is unused
- Move cleaning up and renaming to a separate patch
- Use wait_event_interruptible_timeout() to replace polling
- Remove irq_num from mtk_dsi structure
- Remove redundant and debug codes

Changes since v3:
- Add DSI support for MIPI DSI panels
- Update BLS binding to PWM nodes
- Remove ufoe device nodes
- Remove redundant parentheses
- Remove global variable initialization

Changes since v2:
- Rename mtk_ddp_mux_sel to mtk_ddp_sout_sel
- Update mt2701_mtk_ddp_ext components
- Changed to prefix naming
- Reorder the patch series
- Use of_device_get_match_data() to get driver private data
- Use iopoll macros to implement mtk_disp_mutex_acquire()
- Removed empty device tree nodes

Changes since v1:
- Removed BLS bindings and codes, which belong to pwm driver
- Moved mtk_disp_mutex_acquire() just before mtk_crtc_ddp_config()
- Split patch into smaller parts
- Added const keyword to constant structure
- Removed codes for special memory align

The PATCH depends on the following patch:
https://patchwork.kernel.org/patch/9289401/ ("dt-bindings: ARM: Mediatek: Document bindings for MT2701") 
https://patchwork.kernel.org/patch/9222997/ ("dt-bindings: pwm: Add MediaTek display PWM bindings")
