patch adds "depends on" to L2X0 so that it can be enabled/disabled

The upcoming PB11MPCore and PB1176 have different memory maps and some
of the definitions in platform.h are no longer common. This patch
moves them to the board-eb.h file and updates their usage in
realview_eb.c.

Since the PB1176 has different UART base addresses, this patch moves
the definitions form platorm.h to board-eb.h. It also modifies
uncompress.h to detect the platform type at run-time.

This patch moves the timer definitions from platform.h into board-eb.h
as they are different on PB11MPCore and PB1176. It also adds
timerX_va_base variables in core.c which are set by the
realview_eb_timer_init function before invoking realview_timer_init.

This patch removes the TWD_BASE macro used to set up and configure the

This patch sets the timer IRQ at run-time by moving the sys_timer

This patch modifies the get_irqnr_preamble macro to work with multiple
platforms at run-time by reading the address of the GIC controller from
the gic_cpu_base_addr variable. This variable is defined in core.c and
intialised in realview_eb.c (gic_init_irq).

This patch moves the IRQ and DMA definitions from core.h into
realview_eb.c since they are platform-specific. It adds a
realview_eb11mp_fixup function to adjust the IRQ numbers if the
ARM11MPCore tile is fitted. The realview_smc91x_device is also moved
from core.c into realview_eb.c.

This patch moves the platform specific definitions from platform.h into
the board-eb.h file. It drops the INT_* definitions as they are no
longer used in irqs.h (moved to board-eb.h). It renames REALVIEW_*
macros to REALVIEW_EB_* or REALVIEW_EB11MP_* to distinguish between
standard EB and EB + the ARM11MPCore tile. The platform.h file contains
common definitions to the RealView platforms and it is only directly
included in board-*.h files.

The kernel originally supported revB only. This patch enables revC by
default and adds a config option for building the kernel for the revB
platform. Since the SCU base address was hard-coded in the proc-v6.S
file (and only valid for RealView/EB revB), this patch also adds a
more generic support for defining the SCU information.
