Commit 98c65a3dac95 ("media: si2157: add support for 1.7MHz and 6.1 MHz") introduced two bugs: The 6.1MHz setting was always used for any bandwidth less than 7MHz due to missing "else" keywords, and then the setting was not specified as decimal 10, but as hexadecimal 0x10, which makes the tuner refuse the tune command. In sum, it is not possible to tune to any channels of less than 7MHz bandwidth anymore. Add the missing "else" keywords and convert all bandwidth settings to decimal to avoid any future decimal vs. hexadecimal confusion. Remove the use of the undefined bandwidth setting 0x0f for bandwidths greater than 8MHz, which is also refused by the tune command, in favour of using the default bandwidth setting 8 for any bandwidths greater than 7MHz.
