All device drivers have stopped relying on mach/*.h headers,
so move the remaining headers into arch/arm/mach-lpc32xx/lpc32xx.h
to prepare for multiplatform builds.
The mach/entry-macro.S file has been unused for a long time now
and can simply get removed.

Setting the phy mode requires touching a platform specific
register, which prevents us from building the driver without
its header files.
Move it into a separate function in arch/arm/mach/lpc32xx
to hide the core registers from the network driver.

The lpc_eth driver uses a platform specific method to find
the internal sram. This prevents building it on other machines.
Rework to only use one function call and keep the other platform
internals where they belong. Ideally this would look up the
sram location from DT, but as this is a rarely used driver,
I want to keep the modifications to a minimum.

In the recent change to the reset function API (commit
7b6d864b48), the mode argument changed from a
char to an enum. lpc23xx_restart() only handles REBOOT_SOFT and REBOOT_HARD,
but the new kernel code emits REBOOT_COLD (0) on reboots now which leads to
lpc32xx simply not rebooting (but halting).
This patch fixes this by just resetting unconditionally as on other platforms
(e.g. mach-bcm2835).
Pulling lpc32xx_watchdog_reset() into lpc23xx_restart() since the while() in
lpc23xx_restart() is part of the procedure anyway and lpc32xx_watchdog_reset()
isn't used anywhere else anymore.
