Add the "u-boot,dm-pre-reloc" property to the "ti,tilcdc,panel" compatible node. In this way the video-uclass module can allocate the amount of memory needed to be assigned to the frame buffer. For boards that support Linux the property is added to the *-u-boot.dtsi file since it is a u-boot specific dt flag.
Ran building tests with CONFIG_AM335X_LCD enabled and disabled for the following configurations: - brxre1_defconfig --> success - am335x_guardian_defconfig --> success - am335x_evm_defconfig --> success - da850evm_defconfig --> failure with CONFIG_AM335X_LCD enabled
Enabling CONFIG_AM335X_LCD in da850evm_defconfig causes building errors even without applying the patch. The driver has never been enabled on the da850 and must be adapted for this platform.

Changes in v3: - Add panel to the root node so that the dts linux file of the board does not need to be updated.
Changes in v2: - Change subject line in: arm: dts: am335x: - Move 'u-boot,dm-pre-reloc' property in *-u-boot.dtsi files for boards tha support Linux
