Michal Lenc bf90361895 ioexpander: add support for pcf8575 expander 
This adds support for 16 bit io expander pcf8575. The driver is basically
the same as for pcf8574 however it is for 16 bits instead of 8 bits. Since
pcf8575 and pcf8574 can be both used on the same i2c bus the driver for
pcf8575 is implemented in a different file to reduce the code size
and complexity and to have less if statements in the driver.
