Subject: [PATCH CFT] ARM:VERSATILE: Enable ARM_PATCH_PHYS_VIRT and AUTO_ZRELADDR by default

This patch enables ARM_PATCH_PHYS_VIRT and AUTO_ZRELADDR as default configs
to versatile platform.

Introduction of PHYS_VIRT config as default enables phy-to-virt and virt-to-phy
translation functions at boot and module loading time, and enforce dynamic
reallocation of memory. PHYS_VIRT config is mutually exclusive to XIP_KERNEL,
XIP_KERNEL is used in systems with NOR flash devices.

AUTO_ZRELADDR config enables auto calculation of the decompressed kernel image
address. AUTO_ZRELADDR config is mutually exclusive to ZBOOT_ROM, and also
assumes zImage to be loaded in the first 128MiB from start of memory.

CFT::Call For Testing

Requesting maintainers of Versatile platform to evaluate the changes on the
board and comment, as I dont have the board for testing and also requesting
an ACK.

FTTC broadband for 0.8mile line: 5.8Mbps down 500kbps up. Estimation
in database were 13.1 to 19Mbit for a good line, about 7.5+ for a bad.
Estimate before purchase was "up to 13.2Mbit".
