Modify Tegra's timer code to parse the Tegra timer IRQ from device tree,
and to instantiate the TWD from device tree, rather than relying on hard-

This will allow timer.c to use twd_local_timer_of_register(), and

The Tegra timer provides a number of 29-bit timer channels, a single
32-bit free running counter, and in the Tegra30 variant, 5 watchdog modules.
The first two channels may also trigger a legacy watchdog reset.

When using DEBUG_LL, the UART's (or other HW's) registers are mapped
into early page tables based on the results of assembly macro addruart.
Later, when the page tables are replaced, the same virtual address must
remain valid. Historically, this has been ensured by using defines from
<mach/iomap.h> in both the implementation of addruart, and the machine's
.map_io() function. However, with the move to single zImage, we wish to
remove <mach/iomap.h>. To enable this, the macro addruart may be used
when constructing the late page tables too; addruart is exposed as a
C function debug_ll_addr(), and used to set up the required mapping in
debug_ll_io_init(), which may called on an opt-in basis from a machine's
.map_io() function.
