cover initial suport for Alphascale ASM9260

This is reduced patchset to provide initial support for Alpascale ASM9260.

Oleksij Rempel (2):
ARM: add mach-asm9260
ARM: add lolevel debug support for asm9260

PATCH 1/2 ARM: add mach-asm9260

it is low cost (?) SoC targeted for market in China and India which trying to compete with AT91SAM9G25.

Here is some info:
http://www.alphascale.com/index.asp?ics/615.html

One of products:
http://www.aliexpress.com/store/product/2014-hot-sales-FREE-SHIPPING-new-Purple-core-ARM9-development-board-ASM9260T-SDRAM-power-line/433637_1931495721.html

In some cases this SoC looks similar to iMX23/iMX28. But currently it makes no sense to merge mach code of this devices. Especially because most differences are already collected mach-mxs folder.
