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.
