gpio: pmic-eic-sprd: Add can_sleep flag for PMIC EIC chip

The drivers uses a mutex and I2C bus access in its PMIC EIC chip
get implementation. This means these functions can sleep and the PMIC EIC
chip should set the can_sleep property to true.

This will ensure that a warning is printed when trying to get the
value from a context that potentially can't sleep.
