Fix help for or1k builds
...
The help said cpu-type could be mor1kx, which is correct but you must
pass or1k to get mor1kx. Fix the message to properly represent what
needs to be passed to the commandline.

csr: use external csr_readl()/csr_writel() if present
...
If the variable CSR_ACCESSORS_DEFINED is set, then use external
csr_readl() and csr_writel() instead of locally-generated inline
functions.
With this patch, csr.h can be used with etherbone.h and litex_server to
prototype drivers remotely.

csr: use readl()/writel() accessors for accessing mmio
...
Instead of directly dereferencing pointers, use variants on readl()/writel().
This way we can replace these functions with others for remote access
when writing drivers and code outside of the litex environment.
