iio: light: veml6035: fix read_avail in no_irq case for veml6035

The iio_info is identical for veml6030 and veml6035. Moreover,
veml6035_info_no_irq is missing the initialization of the read_avail
member, which is actually a bug if no irq is provided.

Instead of adding the missing initialization, remove the device-specific
iio_info and use the existing one for the veml6030.
