Write to a PCI or Processor address with a mask

Function PIC_WRITEM - Write to a PCI or Processor address with a mask

PIC	p	Handle to Device 
int	offset	Register Offset
int	*data	Data word (by reference)

Write a register on the PCI Interface or Processor with a mask to enable 
specific bits.  The current register is first read into a scratch word.  The 
bits enabled by mask are transferred from *data into the scratch word, and the 
scratch word is written back to the register.  The Offsets to various
registers are defined in ice21062.h for the SHARC and ice5933.h for the PCI
interface.  This routine returns the final register word as the function status.
