  bcm2835_vcbus: add compatibility name for ^/sys/contrib/vchiq
  
  It's unclear how this didn't get caught in my last iteration, but the fix is
  easy- the interface is still compatible, it was just gratuituously renamed
  to match my arbitrary definition of consistency... VCBUS, the BCM2835 name,
  represents an address on the VideoCore CPU Bus.
  
  In a similar fashion, while it is a physical address, the ARMC portion
  represents that these are addresses as seen by the ARM CPU.
  
  To make things even more fun, the BCM2711 peripheral documentation describes
  not virtual address space vs. physical address space, but instead the 32-bit
  address map vs. the address map in "Low Peripheral" mode. The latter of
  these is what the *ARMC* macros translate to/from.
