Niklas Neronin 757508d6d7 usb: xhci: standardize single bit-field macros 
Convert single bit-field macros to simple masks. The change makes the
masks more universal. Multi bit-field macros are changed in the next
commit. After both changes, all masks in xhci-caps.h will follow the
same format. I plan to introduce this change to all xhci macros.

Bit shift operations on a 32-bit signed can be problematic on some
architectures. Instead use BIT() macro, which returns a 64-bit unsigned
value. This ensures that the shift operation is performed on an unsigned
type, which is safer and more portable across different architectures.
Using unsigned integers for bit shifts avoids issues related to sign bits
and ensures consistent behavior.

Switch from 32-bit to 64-bit?
As far as I am aware, this does not cause any issues.
Performing bitwise operations between 32 and 64 bit values, the smaller
operand is promoted to match the size of the larger one, resulting in a
64-bit operation. This promotion extends the 32-bit value to 64 bits,
by zero-padding (for unsigned).

Will the change to 64-bit slow down the xhci driver?
On a 64-bit architecture - No. On a 32-bit architecture, yes? but in my
opinion the performance decrease does not outweigh the readability and
other benefits of using BIT() macro.

Why not use FIELD_GET() and FIELD_PREP()?
While they can be used for single bit macros, I prefer to use simple
bitwise operation directly. Because, it takes less space, is less overhead
and is as clear as if using FIELD_GET() and FIELD_PREP().

Why not use test_bit() macro?
Same reason as with FIELD_GET() and FIELD_PREP().
