BCM6753 is essentially same as the main chip BCM6855 but with different SKU number. Now that BCM6855 is supported under CONFIG_ARCH_BCMBCA and CONFIG_BCM6855, remove the original ARCH_BCM6753 support and migrate its configuration and dts settings. This includes: - Remove the bcm96753ref board folder. It is replaced by the generic bcmbca board folder. - Merge the 6753.dtsi setting to the new 6855.dtsi file. Update 96753ref board dts with the new compatible string. - Delete broadcom_bcm96763ref.h and merge its setting to the new bcm96855.h file. - Delete bcm96753ref_ram_defconfig and use a basic config version of bcm96855_defconfig
