Similarly to what is done in 32938e12

According to C99, realloc(non_null, 0) != free(non_null), that's why
it is forbidden in QEMU.

When there are no symbols, nsyms equals to 0. Free the syms structure
and set it to NULL instead of reallocating it with a size of 0.

This fixes -kernel with stripped kernels.

Store the register values in native endianness, by dropping all the
endianness conversion functions, and converting the endianness in
dbdma_readl/dbdma_writel instead.

Also guard the endianness conversion with TARGET_WORDS_BIGENDIAN to
simulate the backward connection of the bus.
