911ddb60fc kernel: debug: fix klog on baremetal 
klog() refers to an outdated `.uart` struct, which has since been
renamed to `.serial`.

kernel: Split debug shell and uart driver. 
I've added a `platform` module to store all platform specific code, (not
architecture specific) as some platforms will require custom drivers, e.g.
for debug output and for the random number generation code.  The platform
code is in charge of mapping any peripherals needed to work, also to
initialize any other parts of the kernel that require drivers, for example
the debug shell.

755556611c prep kernel for packaging 
- strip out gdb-stub. Per xobs, the feature never worked, and it
depends upon a branch of a git repo which is not allowed by crates.io
Since the feature hasn't been developed, and crates.io will not
allow even an optional feature that points to a git repo, the feature
was stripped out.

- rename "kernel" to "xous-kernel", so that we can live in a crates.io
package namespace that is specific to Xous.

still have to figure out the riscv package issue.

d42658a65d fix kernel debug input 
for whatever reason, by default, uarts in litex are configured
not to drain a fifo when you read them -- they only drain
after you write EV_PENDING.

this can be used to swap out the println!() function to print to GDB
