AArch32: Add `TRUSTED_BOARD_BOOT` support
This patch adds `TRUSTED_BOARD_BOOT` support for AArch32 mode.
To build this patch the "mbedtls/include/mbedtls/bignum.h"
needs to be modified to remove `#define MBEDTLS_HAVE_UDBL`
when `MBEDTLS_HAVE_INT32` is defined. This is a workaround
for "https://github.com/ARMmbed/mbedtls/issues/708"
NOTE: TBBR support on Juno AArch32 is not currently supported.
