Implement requested PR changes

Removes CFG_TUSB_ALT_BIT_PACKING_ALIGNMENT, and makes the manual padding
behavior standard.  Replaced unused variable name with TU_RESERVED.

The bInterval value is used as the exponent for a \f$ 2^(bInterval-1) \f$ value; e.g., a bInterval of 4 means a period of 8 (\f$ 2^(4-1) \f$). \n- For full-/low-speed interrupt endpoints, the value of this field may be from 1 to 255. \n- For high-speed interrupt endpoints, the bInterval value is used as the exponent for a \f$ 2^(bInterval-1) \f$ value; e.g., a bInterval of 4 means a period of 8 (\f$ 2^(4-1) \f$) . This value must be from 1 to 16. \n- For high-speed bulk/control OUT endpoints, the bInterval must specify the maximum NAK rate of the endpoint. A value of 0 indicates the endpoint never NAKs. Other values indicate at most 1 NAK each bInterval number of microframes. This value must be in the range from 0 to 255. \n Refer to Chapter 5 of USB 2.0 specification for more information.
