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.
