[ARM][PATCH v2] enable FL_LPAE flag for armv7ve cores

The following commit added the FL_LPAE flag to FL_FOR_ARCH7VE, but
neglected to also add it to the armv7ve compatible cores defined in
arm-cores.def.

  https://github.com/gcc-mirror/gcc/commit/af2d9b9e58e8be576c53d94f30c48c68146b0c98

The result is that gcc 6.4 now refuses to allow -march=armv7ve and
-mcpu=XXX to be used together, even when -mcpu is set to an armv7ve
compatible core:

  arm-linux-gnueabi-gcc -march=armv7ve -mcpu=cortex-a7 -Werror ...
  error: switch -mcpu=cortex-a7 conflicts with -march=armv7ve switch [-Werror]

This is a regression relative to gcc 6.3.

Fix by defining flags for armv7ve compatible cores directly from
FL_FOR_ARCH7VE, rather than re-creating the armv7ve flags
independently by combining FL_FOR_ARCH7A with the armv7ve specific
FL_THUMB_DIV and FL_ARM_DIV flags.
