Anatolij Gustschin 09081e5b47 tty: serial: mpc5xxx: fix PSC clock name bug 
mpc512x platform clock code names PSC clocks as "pscX_mclk" but
the driver tries to get "pscX_clk" clock and this results in
errors like:

  mpc52xx-psc-uart 80011700.psc: Failed to get PSC clock entry!

The problem appears when opening ttyPSC devices other than the
system's serial console. Since getting and enabling the PSC clock
fails, uart port startup doesn't succeed and tty flag TTY_IO_ERROR
remains set causing further errors in tty ioctls, i.e.
'strace stty -F /dev/ttyPSC1' shows:

open("/dev/ttyPSC1", O_RDONLY|O_NONBLOCK|O_LARGEFILE) = 3
dup2(3, 0)                              = 0
close(3)                                = 0
fcntl64(0, F_GETFL)                     = 0x10800 (flags O_RDONLY|O_NONBLOCK|O_LARGEFILE)
fcntl64(0, F_SETFL, O_RDONLY|O_LARGEFILE) = 0
ioctl(0, TCGETS, 0xbff89038)            = -1 EIO (Input/output error)

Only request PSC clock names that the platform actually provides.
