spi_mpc83xx: split mpc83xx_spi_work() into two routines

mpc83xx_spi_work() is quite large, with up to five indentation levels and
is quite difficult to read.

So, split the function in two parts:
1. mpc83xx_spi_work() now only traverse queued spi messages;
2. mpc83xx_spi_do_one_msg() only manages single messages.

There should be no functional changes.
