samsung-jflte: Use armv7

I have tested this on xfce4 and weston. I would like to test is on plasma-mobile, but #167 (closed) is getting in the way.

I ran into the following error when compiling the kernel for armv7:

arch/arm/crypto/aesbs-core.S:449: Error: thumb conditional instruction should be in IT block -- `addeq r6,r6,#0x10'
arch/arm/crypto/aesbs-core.S:904: Error: thumb conditional instruction should be in IT block -- `addeq r6,r6,#0x10'
arch/arm/crypto/aesbs-core.S:2100: Error: thumb conditional instruction should be in IT block -- `subne r9,#0x10'

I tried to find a patch, but in the end it was easier to just disable CONFIG_CRYPTO_AES_ARM_BS. Does anyone know if this will lead to any compatibility or performance problems?

This is a WIP until #160 (closed) is complete.
