usb: chipidea: drop "13xxx" infix
"ci13xxx" is bad for at least the following reasons: * people often mistype it * it doesn't add any informational value to the names it's used in * it needlessly attracts mail filters This patch replaces it with "ci_hdrc", "ci_udc" or "ci_hw", depending on the situation. Modules with ci13xxx prefix are also renamed accordingly and aliases are added for compatibility. Otherwise, no functional changes.
