dt-bindings: display: bridge: ldb: Add check for reg and reg-names
...
Make "reg" property mandatory for all LDB devices and "reg-names"
mandatory for i.MX8MP and i.MX93 which have two "reg" values. The
i.MX6SX has only one "reg" value so the "reg-names" property there
is optional and not needed.

i.MX6SX has a single LVDS port and share a similar LDB_CTRL register
layout with i.MX8MP and i.MX93.

dt-bindings: display: bridge: ldb: Add i.MX93 LDB
...
Same to i.MX8mp LDB, i.MX93 LDB is controlled by mediamix blk-ctrl
through 'ldb' register and 'lvds' register. Also, the 'ldb' clock
is required. i.MX93 LDB supports only one LVDS channel(channel 0,
a.k.a, LVDS Channel-A in the device tree binding documentation), while
i.MX8mp LDB supports at most two. Add i.MX93 LDB device tree binding
in the existing i.MX8mp LDB device tree binding documentation.

dt-bindings: display: drop minItems equal to maxItems
...
minItems, if missing, are implicitly equal to maxItems, so drop
redundant piece to reduce size of code.

dt-bindings: display: bridge: ldb: Implement simple Freescale i.MX8MP LDB bridge
...
The i.MX8MP contains two syscon registers which are responsible
for configuring the on-SoC DPI-to-LVDS serializer. Add DT binding
which represents this serializer as a bridge.
