ARM: msm: GCC Version change.

- This reverts commit 1e3bae2. - Changing gcc toolchain to 4.9 version. - Fix linker error of unknown CPU architecture by adding CONFIG_MSM_CORTEX_A7 in the arch options for the GCC. The issue is seen after bump up to gcc-4.9. - Fix section mismatch errors after upgrading gcc to 4.9 version. To fix these errors variables are moved to appropriate sections.
