spi: Switch i2c drivers back to use .probe() After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

spi: Replace all spi->chip_select and spi->cs_gpiod references with function call Supporting multi-cs in spi drivers would require the chip_select & cs_gpiod members of struct spi_device to be an array. But changing the type of these members to array would break the spi driver functionality. To make the transition smoother introduced four new APIs to get/set the spi->chip_select & spi->cs_gpiod and replaced all spi->chip_select and spi->cs_gpiod references with get or set API calls. While adding multi-cs support in further patches the chip_select & cs_gpiod members of the spi_device structure would be converted to arrays & the "idx" parameter of the APIs would be used as array index i.e., spi->chip_select[idx] & spi->cs_gpiod[idx] respectively.

spi: use new `spi_transfer_delay_exec` helper where straightforward For many places in the spi drivers, using the new `spi_transfer_delay` helper is straightforward. It's just replacing: ``` if (t->delay_usecs) udelay(t->delay_usecs); ``` with `spi_transfer_delay(t)` which handles both `delay_usecs` and the new `delay` field. This change replaces in all places (in the spi drivers) where this change is simple.

spi: xcomm: Export I2C module alias information The I2C core always reports the MODALIAS uevent as "i2c:<client name" regardless if the driver was matched using the I2C id_table or the of_match_table. So the driver needs to export the I2C table and this be built into the module or udev won't have the necessary information to auto load the correct module when the device is added.

So we can remove the same logic in spi_xcomm_setup_transfer(). Also remove a redundant code to initialize is_first variable.
