csr_bus: Honour re signal from the upstream bus 
Currently CSR bus assumed that ~we means reading, that created
a problem that when for a CSR if reading has side effects and adr
parked unintentionally at that CSR, the reading side effect will be
triggered.

For SoCs, this happened when upstream bus issued a write transaction
with wishbone.sel, then on CSR bus it will be translated
as adr = addr, we = 0, which will be interpreted as a read to such
address, and trigger undesired side effect for such CSR.

Such upstream transaction will be generated by our bus width converter.

Given that we signal already presents in CSR Interface, the easiest way
to handle such situation is to generate re signal at bus bridges and
propagate it all the way down to the Interface.

soc/integration/soc.py: Fix creation of AHB2Wishbone bridge 
Don't do bus_addressing_convert as it's being handled in AHB2Wishbone
logic.

Add addressing parameters for AHBInterface constructor as required
by soc code.

integration/soc: data_width_convert: Inherit more bus properties 
For data_width converter we need to ensure that adapted interface
have same properties as it's parent interface, so that id and user
signals for AXI will be propagated properly from parent to adapted
interface.
