board: turris: Move Turris Atsha OTP code to separate file OTP code is not Atsha generic but also it is not Omnia specific. It is common for all Turris routers which use Atsha cryptochip for storing OTP. So move this common Turris specific Atsha OTP code from Turris Omnia into separate file. It will be used also by other Turris routers.

board: turris: Allow to specify first eth idx of first MAC address Turris Omnia uses first MAC address from OTP for second ethernet interface. Second MAC address for third interface and third MAC address for first interface. Other Turris routers do not have this rotate by one mapping. So add function parameter for specifying id of the first ethernet interface.

board: turris: Initialize serial# env Store serial number from atsha cryptochip into the serial# env variable. U-Boot automatically puts content of this variable into the root device tree property serial-number when booting Linux kernel. Refactor turris atsha code and from turris_atsha_otp_get_serial_number() function returns directly string suitable for printing or storing into device tree. Because during different boot stages is env storage read-only, it is not possible to always store serial number into env storage. So introduce a new function turris_atsha_otp_init_serial_number() which is called at later stage and which ensures that serial number is correctly stored into env.
