a57f0640cc soc/interconnect/csr: Add optional support fixed CSR mapping.
By default, location is still automatically determined but it's now possible to
specific locations:

The following module:

class MyModule(Module, AutoCSR):
    def __init__(self):
        self.csr0 = CSRStorage()
        self.csr1 = CSRStorage(n=0)
        self.csr2 = CSRStorage(n=2)

built on a SoC with 32-bit CSR data-width will have the following CSR mapping:
- 0x00 : csr1
- 0x04 : csr0
- 0x08 : reserved
- 0x0c : csr2
