As requested by Arnd Bergmann, the hvc drivers are now
moved to the drivers/tty/hvc/ directory. The virtio_console.c driver
was also moved, as it required the hvc_console.h file to be able to be
built, and it really is a hvc driver.

This is nicer for modern R/O protection. And noone needs it non-const, so
constify the callers as well.

So the iSeries console will be faster since it can send up to 200 bytes at
a time to the Hypervisor. This only affects the tty part of the console,
the console writes are still in 16 byte lots.

A few cleanups in hvc_rtas.c:
1. Remove unused RTASCONS_PUT_ATTEMPTS
2. Remove unused rtascons_put_delay.
3. Use i as a loop counter like everyone else on earth.
4. Remove pointless variables, eg. x = foo; if (x) return something_else;
5. Whitespace cleanups and formatting.

Current Cell hardware is using the console through a set
of rtas calls. This driver is needed to get console
output on those boards.
