Aligning block_buffer to uint32_t
block_buffer will eventually be used by the flash_write_buffer() implementation
of the NOR driver for the Juno board. That implementation requires the buffer
passed to it to be 32bit aligned, which might not be enforced depending on
the compiler optimizations.
This patch will enforce that alignment on all cases.
