In APM8018X SOC, UART register address space has been relocated to 32-bit
data boundaries for APB bus implementation.
Current legacy_serial driver ignores the reg-shift property. This patch
modifies legacy_serial.c and udbg_16550.c to work with above mentioned UARTs.

No refcounting, just a switch. The locking in the driver prevents
races, so in fact the refcounting is not needed. But while we have a
tty in tty_port, don't duplicate that and remove the one from
hvcs_struct.

The driver already used refcounting. So we just switch it to tty_port
helpers. And switch to tty_port-lock for tty.

Now, count is used from tty_port and protected by tty_port-lock.
n_outbuf is left unprotected in hvc_hangup now, because there is no
point to hold any lock, since other uses are unprotected too.

It is in termios cflags. So change the test in hvsi_recv_control to do
the right thing. Previously it was actually testing TTY_LDISC_OPEN
