ARM: zynq: Enable the Neon instructions Added the lowlevel_init to enable the Neon instructions. Initially the u-boot was causing undefined instruction exception if loaded through tcl, and working fine if loaded through FSBL. The exception was causing in convertion formula of given time to ticks. It was because, the Neon instructions were disabled and hence causing the undefined exception. In FSBL case, the FSBL was enabling the Neon instructions. Hence, added the lowlevel_init to enable the Neon instructions. Also enable neon instructions for non-xilinx toolchain.
