2022-10-13mb/prodrive/hermes: Harden `eeprom_read_serial()`Angel Pons
The `eeprom_read_serial()` function could return a non-NULL terminated string if the serial in EEPROM has `HERMES_SN_PN_LENGTH` (32) non-NULL characters. Make this impossible by adding an additional character for a NULL byte in the static buffer, which always gets set to 0 (NULL).

2022-10-11mb/prodrive/hermes: Make board settings less error-proneAngel Pons
First of all, make sure that `get_board_settings()` never returns NULL. If there's a problem, return predefined values for board settings. If the board settings definition differs between coreboot and the BMC, the CRC will not match. Allow coreboot to use the BMC settings provided by older BMC firmware revisions which have less settings, if the CRC of the first N bytes matches the expected CRC. TEST=Boot coreboot master with BMC FW R04.05, observe board settings being honored even though coreboot's definition has an extra option.

2022-10-08mb/prodrive/hermes: Add part numbers to SMBIOSAngel Pons
Adjust the EEPROM layout to account for two new fields: board part number and product part number. In addition, put them in a Type 11 SMBIOS table (OEM Strings). Also, rename a macro to better reflect its purpose.

2022-10-07mb/prodrive/hermes: Factor out serial reading logicAngel Pons
Add the `eeprom_read_serial()` function to read serials from the EEPROM. Note that there's only one buffer now: this means only one serial can be accessed at the same time, and the buffer needs to be cleared so that it does not contain old data from other serials. Given that the serials are copied one at a time into SMBIOS tables, having one shared buffer is not a problem.

2021-12-03mb/prodrive/hermes: Clean up some cosmeticsAngel Pons
Use lowercase for hex numbers, sort includes alphabetically and avoid relying on indirect inclusion. Include `<intelblocks/gpio.h>` instead of `<intelblocks/gpio_defs.h>`, as the latter implcitly relies on one definition from `<soc/gpio.h>`. Also drop useless dsdt.asl and fix up the indentation of some includes. Tested with BUILD_TIMELESS=1, Prodrive Hermes remains identical.

2021-12-03mb/prodrive/hermes: Get rid of variant structureAngel Pons
There's no need to use a variant structure here. Only one variant is used, and revision-specific differences are handled at run-time, and it's unlikely that another variant will ever exist.

In addition, reduce the scope of the `I2C_ADDR_EEPROM` definition, since using it outside of eeprom.c would bypass the API's abstraction layer.
