memory: ti-emif-sram: only build for ARMv7

The driver can be compile-tested on all ARM machines, but
causes a failure when built for ARMv7-M:

arm-linux-gnueabi-ld: error: drivers/memory/ti-emif-sram-pm.o: conflicting architecture profiles A/M

Limit the target machines to configurations that have ARMv7 enabled.

Fixes: ea0c0ad6 ("memory: Enable compile testing for most of the drivers")
