serial: imx: add wrappers for writel and readl
This prepares implementing shadow copies for the control registers and
additionally provides a good place to hook in debug code to trace
register usage.
Most of this patch was done using pattern substitution:
perl -p -i -e '
s/\breadl(?:_relaxed)?\((?:sport->port\.|port->)membase \+/imx_uart_readl(sport,/;
s/\bwritel(?:_relaxed)?\(([^,]*), (sport->port\.|port->)membase \+/imx_uart_writel(sport, $1,/;
