iio: frequency: adf4377: Fix duplicated soft reset mask
commit 6c8bf4b604a8a6346ca71f1c027fa01c2c2e04cb upstream.
The regmap_read_poll_timeout() uses ADF4377_0000_SOFT_RESET_R_MSK
twice instead of checking both SOFT_RESET_MSK (bit 0) and
SOFT_RESET_R_MSK (bit 7). This causes an incomplete reset status check.
The code first sets both SOFT_RESET and SOFT_RESET_R bits to 1 via
regmap_update_bits(), then polls for them to be cleared. Since we set
both bits before polling, we should be waiting for both to clear.
Fix by using both masks as done in regmap_update_bits() above.
