i2c-eg20t: change timeout value 50msec to 1000msec
Currently, during i2c works alone, wait-event timeout is not occurred.
However, as CPU load increases, timeout occurs frequently.
So, I modified like this patch.
Modifying like this patch, I've never seen the timeout event with high
load test.

i2c-eg20t: Rework pch_i2c_wait_for_bus_idle to reduce wait time
If you insert several i2c transfers, the driver might start the next one
while the STOP bit of the previous transfer is still on the bus, marking
the bus as busy.
pch_i2c_wait_for_bus_idle does an msleep(20) delaying the next transfer
by >=20ms. Reduce wait time by actively waiting 5 us once, then using
usleep_range.

i2c-eg20t: correct the driver init order of pch_i2c_probe()
Before registering an adapter to i2c subsystem, we need make sure
driver is ready for incoming i2c xfer, becasue the i2c_add_adapter()
may trigger a i2c device driver's proble function which may start
some real i2c xfer. I met this issue when integrating a TSC2007 i2c
touch screen device with the i2c-eg20t driver.
This patch will call request_irq() and hw init before calling
i2c_add_adapter().

However currently, the processing is continued.
This patch breaks the processing.

Currently, pch_i2c_xfer returns read/write size at that time.
However pch_i2c_xfer must return the number of messages to be read/written.
