Paul Menzel 56642930ab mb/lenovo: Prepend EC event number with 0x to denote hex notation
Currently, the message below is printed, suggesting it’s decimal
notation:

    coreboot-4.12-1530-g7acbd5fc45 Sun Jul 19 07:47:58 UTC 2020 smm starting (log level: 7)...
    EC event 48
    GPI (mask 1000)

Prepend 0x, so it’s clear it’s hexadecimal notation.

    EC event 0x48

Use the command below change all places:

    git grep -l 'EC event %02x' | xargs sed -i 's/EC event %02x/EC event %#02x/'
