Michal Sieron 5b166b3aa4 Fix microwatt synthesis 
Microwatt uses now 29 bit wishbone addresses, so 3 additional bits for
compatibility are no longer needed.

Rest is minimal set of changes that was needed to make it build.

Florent Kermarrec fd354c5759 gen/fhdl/memory: Fix dual clock memory pattern (previous pattern is no longer supported by Yosys), thanks @gregdavill.

Florent Kermarrec 8fbd1b84a4 gen/fhdl: Use a local emit_verilog function for Memory. 
With the various FPGA now supported, being able to generate valid verilog patterns
that will be infered correctly is now complicated.

Use our local version of emit_verilog to be able to specialize more easily the generated
code.

This will also allow use to progressively remplace Migen's Memory.

Joel Stanley 79ae6a99ab microwatt: Fix family property 
In commit 061b89beff ("cpu/picolibc: Add family property to CPUs and
directly use it for picolibc.") a family was added for meson cross
compilation, but this doesn't exist, leading to the following warning:

 WARNING: Unknown CPU family powerpc, please report this at https://github.com/mesonbuild/meson/issues/new

Instead use ppc64. While this seems wrong for a ppc64le machine, it
appears to be what meson expects.

Florent Kermarrec 99f3498f2d cores/icap/ICAP: Add Register read capability. 
Useful to get some internal status, ex the IDCode or know if the executed bistream

Jakub Piecuch 771897fa37 cpu/rocket: naturally align data defined in crt0.S 
The startup code accesses this data using sd/ld instructions, which
require that the address being accessed is 8-byte aligned.
The .dword asm directive does NOT imply any alignment, so we need
to force it using the .align directive.
