arch/x86: Init firmware pointer for EC SMSC KBC1098/KBC1126 at build time
According to util/kbc1126/README.md, for these ECs to work, the
address and size of their two firmware should be written to $s-0x100`
(`$s` means the image size, done with kbc1126_ec_insert), which means
that every existing section (especially those used to store code)
should not overlap this address, otherwise the bootblock will get
damaged when inserting firmwares of the EC.
In this commit, ecfw_ptr is a structure initialized at build time
according to CONFIG_KBC1126_FW1_OFFSET and CONFIG_KBC1126_FW2_OFFSET
(to do so, they should be redefined as hex), and linked to
CONFIG_ECFW_PTR_ADDR within bootblock, so kbc1126_ec_insert is not
needed at build time any more.
Test passed on Elitebook Folio 9470m.
