John Youn f044af8c1d usb: ch9: Add size macro for SSP dev cap descriptor
commit 446fa3a95df1e8b78f25e1babc41e46edd200821 upstream.

The SuperspeedPlus Device Capability Descriptor has a variable size
depending on the number of sublink speed attributes.

This patch adds a macro to calculate that size. The macro takes one
argument, the Sublink Speed Attribute Count (SSAC) as reported by the
descriptor in bmAttributes[4:0].

See USB 3.1 9.6.2.5, Table 9-19.
