[PATCH 1/4] Revert "dt-bindings: display: bridge: ldb: Add check for reg and reg-names"

This reverts commit 8aa2f0ac08d3b207ba54e98698c9d696b86452a7.

The LDB is either part of the IOMUX_GPR (i.MX6SX) or the BLKCTRL
(i.MX8MP, i.MX93) register space. Both IOMUX_GPR and BLKCTRL are
register ranges with loose register definitions. E.g.

  - On the i.MX8MP there is one register which controls the AXI
    threshold for two different IPs (BIT(31:16) - IP1, BIT(15:0) - IP2).
  - On the i.MX6SX IOMUXC_GPR5 controlls: CSI2 mux, WDOG3 settings, PXP
    handshake, ...

In conclusion: it can't be ensured that one register belongs to one
dedicated IP and the LDB is rather an exception than the rule.

Therefore remove the 'reg' and 'reg-names' property requirement.
