Shutdown properly the timer counter block by masking interruptions. Otherwise,
a segmentation may happen when kexec-ing a new kernel (see backtrace below).
An interruption may happen before the handler is set, leading to a kernel
segmentation fault.

Furthermore, we make sure the interruptions are masked when the driver is
initialized. This will prevent freshly kexec-ed kernel from crashing when
launched from a kernel which does not properly mask interruptions at shutdown.

The backtrace below happened after kexec-ing a new kernel, from a kernel
that did not shut down properly leaving interruptions unmasked.

Move resource retrieval from atmel_tc_alloc to tc_probe to avoid lately
reporting resource related issues when a TC block user request a TC block.

Moreover, resources retrieval are usually done in the probe function,
thus moving them add some consistency with other drivers.

Initialization is done once, ie not every time a tc block is requested.
If it fails, the device is not appended to the list of tc blocks.

Furhermore, the device id is retrieved at probe as well, avoiding parsing
DT every time the user requests of tc block.

Add a Kconfig entry for R-Mobile SoCs that enables
both CMT and TMU timers. Interrupt controller varies
with SoC version so it is excluded.

mx1ads.c can be replaced with devicetree equivalent: imx1-ads.dts,
so remove the board file.

With commit c716483c ("ARM: 8122/1: smp_scu: enable SCU standby
support"), the STANDBY bit of SCU is handled by core function
scu_enable().  So imx_scu_standby_enable() can be removed now.

The iomux function declarations are in headers only accessible in this
directory. Thus those can't be used in any module. None of the
objects in this directory is tristate. Neither can the header be included
in out-of-tree modules.

Pull Xtensa updates from Chris Zankel:
 "Xtensa improvements for 3.17:
   - support highmem on cores with aliasing data cache.  Enable highmem
     on kc705 by default
   - simplify addition of new core variants (no need to modify Kconfig /
     Makefiles)
   - improve robustness of unaligned access handler and its interaction
     with window overflow/underflow exception handlers
   - deprecate atomic and spill registers syscalls
   - clean up Kconfig: remove orphan MATH_EMULATION, sort 'select'
     statements
   - wire up renameat2 syscall.

  Various fixes:
   - fix address checks in dma_{alloc,free}_coherent (runtime BUG)
   - fix access to THREAD_RA/THREAD_SP/THREAD_DS (debug build breakage)
   - fix TLBTEMP_BASE_2 region handling in fast_second_level_miss
     (runtime unrecoverable exception)
   - fix a6 and a7 handling in fast_syscall_xtensa (runtime userspace
     register clobbering)
   - fix kernel/user jump out of fast_unaligned (potential runtime
     unrecoverabl exception)
   - replace termios IOCTL code definitions with constants (userspace
     build breakage)"
