    gpio: pmic-eic-sprd: Add can_sleep flag for PMIC EIC chip
    
    [ Upstream commit 26d9e5640d2130ee16df7b1fb6a908f460ab004c ]
    
    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.
