sensor: bme280: Fix bad chip id read after power cycle

Fix an issue where the BME280 sometimes returns an incorrect chip ID
immediately after a power cycle. This causes sensor initialization to fail.

According to the datasheet, the sensor requires a 2 ms start-up delay after
power is applied. This patch introduces a sleep delay to ensure the
required start-up time is respected before reading the chip ID.
