misc: zynq-slcr: Rewrite
Near total rewrite of this device model. It is stylistically obsolete, has numerous coverity fails and is not up to date with latest Xilinx documentation. Fix. The registers are flattened into a single array. This greatly simplifies the MMIO accessor functions. We take the oppurtunity to update the register Macro definitions to match the latest TRM. Xilinx has de-documented some regs hence there are some straight deletions. We only do this however in the case or a stock read-as-written reset-zero register. Non-zero resets are always preserved. New register definitions are added as needed. This all comes with a VMSD version break as the union layout from before was a bit strange and we are better off without it.
