size_t is an unsigned type and as such is a bad choice for a counting

The WG (write gate) bit in C0_EBase allows the upper two bits of
the exception base address to be set to something other than 2'b10,
thus allowing it to be relocated out of the traditional KSEG{0,1}
range. Since we're not using the segmentation features introduced
by EVA to relocate the unmapped segments, the exception vectors
should remain in KSEG0. Don't set the WG bit so that the upper
two bits of the exception base (2'b00, because of the identity
mapping) are ignored and we execute the exception vectors out of
KSEG0.

Add helper macros to convert between physical addresses and KSEG{0,1}
addresses. Also get rid of the virt_to_{bus,phys}_offset variables
as these are fixed values.
As nobody seems to be using getpagesize() on MIPS, no need to keep
virtual.c.

Use bus_to_virt() to convert the physical address of the DMA
coherent region to an address in KSEG1 which is suitable for

Now that coreboot has identity-mapped DRAM, use base address 0 (KUSEG)
instead of 0x80000000 (KSEG0).

The default string functions work with multiple of 4 bytes
(sizeof(unsinged long)); MIPS will use LW/SW instructions
for these operations and if the source and destination
addresses are not aligned it will trigger an exception.
Therefore, this implementation does all data access operations
per byte, because there is no guarantee that the provided
strings are properly aligned.
