The bmm350_prep_reg_write_rtio_async() function was incorrectly using two separate SQEs for register writes, creating two distinct I2C transactions: Before: [START][ADDR+W][REG][RESTART] + [START][ADDR+W][DATA][STOP]
Change to use a single SQE for the entire write:
After: [START][ADDR+W][REG][DATA][STOP]
