iio: imu: inv_mpu6050: add support for IAM-20680HT/HP

Browse Source 
IAM-20680HT & HP are 2 variants of IAM-20680 with better specs,
wider temperature range, and a bigger FIFO (4k).

Fully compatible with IAM-20680, FIFO is 512 bytes by default and
with correct register setting we expand it to full 4k.
