Do not generate seperate comparisons for cpu interface mux
Rather, use the activate-signals that get generated anyway.

Extend test_simple_rw_reg with 3 more tests
The following tests are now included:

    - Check access to registers over AHB bus
    - Check access to register over HW interface
    - Check access to register over HW interface if hw_wr-input
      is disabled.
    - Check if the slave responds with a correct error sequence if
      an illegal address is accessed.

Fix external-register bug where the sw_rd-wire is missing
This was introduced in dc37c879 because sw_rd-wires got removed
here for registers that don't need it.

Fix bug in external read-interface
In dc37c879, some properties got saved in self.properties of a
Component. In that commit, self.properties['sw_rd'] never got set.
For that reason, external registers with a read-interface were broken.

Repair multi-enumerations in one regfile bug
When a regfile did use enumerations from multiple scopes this messed up
the eventual packages because every regfile only assumed 1 scope. This
is fixed now.

TODO: Check what happens if enums are defined in the register scope.

Finish initial version of interrupt suport, closes #1
The software is now able to create most interrupt combinations of
Section 9.9 of the SystemRDL 2.0 LRM. It supports
stickybit/non-stickybit interrupts, it support posedge, negedge,
bothedge, and level interrupts, and it is able to generate all
surrounding logic.

This commit also fixes a reset-bug that caused registers that were reset
to 0 to be not reset (because 'if not reset_value' will return True if
the 'reset_value' is 0).

Add basic interrupt framework
Up to this point, interrupt outputs are generated and intr, enable,
mask, haltenable, and haltmask are supported. stick, stikcybit and the
different types of interrupts are not yet supported.

This commit also removes the option to turn off santiy checking. This is
a bad idea anyway...

Replace old 'reg_clk' name by more generic 'clk'
The reason is that the template will always assume that the
bus signals and the registers are synchronous. Designers should
implement possible synchronization logic outside of this block.

Fix two issues to get AMBA widget compile clean under Verilator
The former issue was a Lint warning. HADDR % HSIZE is a modulo operation
of a 32-bit and 3-bit variable. It is cleaner to only use the LSB of
HADDR.

Furthermore, Verilator does not support unpacked arrays in packages.

Resolve bug for addrmaps without any genvars
In this case, there would be a line with `genvars ;`. This is not
compilable by SystemVerilog compilers.

Add support for external registers
Every single field and every single alias (!) has its own
interface to the surrounding hardware. This is required
to give users the maximum amount of freedom when defining
certain properties in RDL.

Add proper support for rdy & error indication in read multiplexer
The error indication is generated if:
    - A non-existent register gets read
    - An existent register gets read but not a single bit can be
      succesfully read or written. As soon as 1 bit succeeds don't
      return an error.
