Benjamin Herrenschmidt bf1b98b958 litedram: Add support for booting without BRAM

payload stashed along with the init code in the secondary BRAM
into DRAM and boot from there

We might want a non power of 2 amount of RAM in order to fit into an
FPGA, so create log2ceil and use it when calculating the number of
memory bits.
