[PATCH v2 00/13] usb: xhci: Host Controller Capability Registers rework

[Niklas Neronin <niklas.neronin@linux.intel.com>]

This patch series focuses on improving the definitions and organization of
the Host Controller Capability Registers macros in the xhci driver.
It is the first step in a larger effort to clean up and restructure the
xhci header files for better readability and maintainability.

Because the Structural Parameters 1 register (part of the HC Capability
Registers) relies heavily on xhci-caps.h, a few related patches from
another ongoing rework have been included here as well. These address the
handling of Max Ports and Max Interrupters values.
The Max Slots handling will follow the same pattern in a future series.
That change is more involved and will be submitted separately.

v2 changes:
 * Change xhci_ist_in_microseconds() argument to 'xhci'.
 * Rename xhci_ist_in_microseconds() to xhci_ist_microframes().
 * Revert to (1 << x) from BIT() operaion in HCC_MAX_PSA() macro.
 * Added macro changes to DWC3 driver.
