Subject: [PATCH] tools/litex_json2dts_linux.py: update mmc node

Add `reg-names` property, which facilitates cleaner probing
for the upstream Linux device driver. Also, add a reference
to the LiteX sys_clk, also for the benefit of the upstream
driver, which can't rely on the CPU frequency matching sys_clk.
