5e34b313ee RegMapper: regmap(...) now takes BYTE addresses
If a device has configurable bus-width, we need a stable way of
enumerating registers. The byte offset stays unchanged.

This change also makes it possible to put an arbitrary number of RegFields
starting at some address which are then chopped up into appropriately bus-
sized registers.

972ca06729 RegField: remove RegField.bytes; it was dangerous
The implementation unconditionally drove the register.
This made it incompatible with drivers from the device itself.
Besides, writing only parts of a register at a time is ultra-shady.

a421469754 tilelink2: change adapters to use TLAdapter(params, defaults)(node)
This API makes it much more readable when you have multiple adapters
combined into a single line. The arguments for each adapter stay
beside the adapter.

For example, this:
  peripheryBus.node := TLWidthWidget(TLBuffer(TLAtomicAutomata()(TLHintHandler(legacy.node))), legacy.tlDataBytes)
becomes this:
  peripheryBus.node := TLWidthWidget(legacy.tlDataBytes)(TLBuffer()(TLAtomicAutomata()(TLHintHandler()(legacy.node))))
