ramips: lzma-loader: use default uart for rt305x

Browse Source 
The rt305x series SOC have two UART devices,
and the one at bus address 0x500 is disabled by default.
Some boards do not even have a pinout for the first one,
so use the same one that the kernel uses at 0xc00 instead.

This allows the lzma-loader printing to be visible
alongside the kernel log in the same console.
