backlight: mp3309c: Fix uninitialized local variable
In the function "pm3309c_parse_dt_node", when the dimming analog control
mode (by I2C messages) is enabled, the local variable "prop_levels" is
tested without any initialization, as indicated by the following smatch
warning:
drivers/video/backlight/mp3309c.c:279 pm3309c_parse_dt_node() error: uninitialized symbol 'prop_levels'.
To avoid any problem in case of undefined behavior, we need to initialize
it to "NULL".
