This also fixes a sparse warning about different signedness.
Only compile tested, because i do not have the hardware.

In a few places, sdio_uart_irq() is called directly instead of waiting
for the actual interrupt to be raised and the SDIO IRQ thread scheduled
in order to reduce latency. However, some interaction with the tty core
may end up calling us back (serial echo, flow control, etc.) creating
two issues:
- the host lock gets claimed twice from the same thread causing a
deadlock;
- the same direct calls to sdio_uart_irq() may be performed causing
unexpected reentrancy into the IRQ handler.
This patch handles both of those issues.

Note that the default baudrate is 4800 instead of 9600 as a convenience
because that's what GPS devices want which is still the main use for
this driver.

This mimics what the serial_core does. Useful for diagnostics.

This currently only accepts the GPS class since that's all I have for
testing. Tested with a Matsushita GPS and gpsd version 2.34.
