target-mips: add Unified Hosting Interface (UHI) support
Add UHI semihosting support for MIPS. QEMU run with "-semihosting" option will alter the behaviour of SDBBP 1 instruction -- UHI operation will be called instead of generating a debug exception. Also tweak Malta's pseudo-bootloader. On CPU reset the $4 register is set to -1 if semihosting arguments are passed to indicate that the UHI operations should be used to obtain input arguments.
