[PATCH v8 22/24] drm: rockchip: Add VOP2 driver

[Sascha Hauer <s.hauer@xxxxxxxxxxxxxx>]

From: Andy Yan <andy.yan@xxxxxxxxxxxxxx>

The VOP2 unit is found on Rockchip SoCs beginning with rk3566/rk3568.
It replaces the VOP unit found in the older Rockchip SoCs.

This driver has been derived from the downstream Rockchip Kernel and
heavily modified:

- All nonstandard DRM properties have been removed
- dropped struct vop2_plane_state and pass around less data between
  functions
- Dropped all DRM_FORMAT_* not known on upstream
- rework register access to get rid of excessively used macros
- Drop all waiting for framesyncs

The driver is tested with HDMI and MIPI-DSI display on a RK3568-EVB
board. Overlay support is tested with the modetest utility. AFBC support
on the cluster windows is tested with weston-simple-dmabuf-egl on
weston using the (yet to be upstreamed) panfrost driver support.

Notes:
    Changes since v6:
    - Drop device tree parsing during runtime
    - Fix typo in Kconfig help text
    
    Changes since v5:
    - consistently use u8/u16/u32 rather than uint8_t/uint16_t/uint32_t
    - Use spin_lock rather than spin_lock_irqsave
    - replace printk with drm_dbg
    - break some overlong lines
    
    Changes since v4:
    - Avoid stack frame overflow by not allocating big array on the stack
    
    Changes since v3:
    - Sort includes
    - fix typos
    - Drop spinlock
    - Use regmap_set_bits()/regmap_clear_bits()
    - simplify vop2_scale_factor()
    - simplify vop2_afbc_transform_offset()
    
    Changes since v4:
    - Sort nodes alphabetically
    
    Changes since v3:
    - Fix HDMI connector type
    
    Changes since v4:
    - Add Robs Ack
    
    Changes since v3:
    - Bring back gamma_lut regs
    - Drop redundant _vop suffix from clock names
    
    Changes since v5:
    - Drop unnecessary #size-cells/#address-cells from nodes with only single endpoint
