soc/interconnect: remove axi_lite
...
axi_lite code was defining AXI4Lite signals and doing a AXI4Lite bridge to the
CSR bus when LiteX was not having proper AXI support. LiteX now has proper AXI
support and it also cover what axi_lite was doing: To create a AXILite to CSR
bus, user can create an AXILite2Wishbone bridge and then connect the CSR bus
directly to the wishbone bus as done in the others non-AXI SoC.

integration/soc_core: rework interrupt assignation/reservation
...
The CPUs can now reserve specific interrupts with reserved_interrupts property.
User can still define interrupts in SoCCore.interrupt_map (old way) or use
add_interrupt method. Interrupts specific to SoCCore internal modules are
allocated automatically on the remaining free interrupt ids.
Priority for the interrupts allocation:
- 1) CPU reserved interrupts.
- 2) User interrupts.
- 3) SoCCore interrupts.

soc/integration/cpu_interface: more arch-specific address size fixes
...
When generating arch-specific include files (generated/[mem|csr].h)
ensure address literal defines are suffixed by 'L', denoting their
'unsigned long' type. This inhibits compiler warnings when values
computed based on these constants are cast to pointers.
Also ensure csr_[read|write][b|w|l]() function declarations have
'unsigned long' address arguments.
Finally, restore the correct (32-bit, (unsigned *)) expected
behavior of the MMPTR() macro, inadvertently converted to an
arch-specific sized access (unsigned long *) by commit 5c2b8685
