[NTOS]: Make system startup match x86 code as closely as possible, instead of mixing MIPS/PPC code. Only rip out parts that are obviously x86-specific. Also fix code to use new KPCR definitions.
[NTOS]: Implement a DbgPrintEarly function that directly uses KDCOM to print to the serial console, instead of going through the Debug Service Interrupt. svn path=/trunk/; revision=45513
