xhci: dbc: prepare to expose strings through sysfs
Reorganize the code to prepare ground for setting serial number,
product and manufacturer names through sysfs. This commit:
1. Introduces new buffers for storing serial number, product and
manufacturer name in utf8. The buffers will be used by sysfs
*_show and *_store functions.
2. Increases USB string descriptor data maximum length to the
value from USB specification (126 bytes of data).
3. Adds new helper functions get_str_desc_len, prepare_len
and xhci_dbc_populate_str_desc.
