[U-Boot] [PATCH 1/3] arm: Add SYS_L2CACHE_OFF Kconfig entry

To i.MX6UL, SYS_L2CACHE_OFF is selected, but there is no Kconfig entry
for SYS_L2CACHE_OFF. Then "select SYS_L2CACHE_OFF" does not effect for
i.MX6UL, which is not expected.

Since SYS_L2CACHE_OFF is mainly used by ARM architecture, add it to
arch/arm/Kconfig.

Hi,

I worked this patch based on imx tree, since mainly for i.MX6UL. Then
can this patch go through imx tree to avoid break i.MX6UL? This option
does not impact others which defined CONFIG_SYS_L2CACHE_OFF in board
header file.
