The SPDX License List version 1.19 now contains an official entry for the IBM-pibs license. However, instead of our suggestion "ibm-pibs", the SPDX License List uses "IBM-pibs", with the following rationale: "The reason being that all other SPDX License List short identifiers tend towards using capital letters unless spelling a word. I'd prefer to be consistent to this end". Change the license IDs to use the official name. Signed-off-by: Wolfgang Denk <wd@denx.de>
