serial: tegra: Define correct port type
When doing the cat /proc/tty/driver/tegra_uart, the serial
core display the message as
0: uart:unknown port:00000000 irq:68 tx:0 rx:0 CTS|DSR|CD|RI
4: uart:unknown port:00000000 irq:123 tx:0 rx:0 CTS|DSR|CD|RI
This is because the correct port type and iotype are not getting
set in tegra serial driver.
Setting these parameter to proper to display the information as
1: uart:TEGRA_UART mmio:0x70006040 irq:69 tx:0 rx:0 CTS|DSR|CD|RI
2: uart:TEGRA_UART mmio:0x70006200 irq:78 tx:477 rx:1603 RTS|CTS|DTR|DSR|CD|RI
3: uart:TEGRA_UART mmio:0x70006300 irq:122 tx:0 rx:0 CTS|DSR|CD|RI
4: uart:TEGRA_UART mmio:0x70006400 irq:123 tx:0 rx:0 CTS|DSR|CD|RI
