BCM68360 is a variant within the BCM6856 chip family. Now that BCM6856 is supported under CONFIG_ARCH_BCMBCA and CONFIG_BCM6856, remove the original ARCH_BCM68360 support and migrate its configuration and dts settings. This includes: - Remove the bcm968360bg board folder. It is replaced by the generic bcmbca board folder. - Merge the 68360.dtsi setting to the new 6856.dtsi file. Update board dts with the new compatible string. - Merge broadcom_bcm968360bg.h setting to the new bcm96856.h file. - Remove bcm968360bg_ram_defconfig as a basic config version of bcm96856_defconfig is now added.

(no changes since v3)
Changes in v3: - Remove bcm968360bg_ram_defconfig per discussion with Philippe as a basic config version of bcm96856_defconfig is now added. - Update commit message
Changes in v2: - Bring Philippe Reynes copyright tag from 68360 dts to 6856 dts
