HID: split picolcd's operation_mode sysfs attribute
Original operation_mode sysfs attribute accepts the operation mode
as main value with an option delay as second value to change
the start-up delay on mode change.
As it is preferred to have exactly one value per sysfs attribute,
extract this delay into a separate sysfs attribute called
operation_mode_delay.
