One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
void *entry[];
};
instance = alloc(sizeof(struct foo)
The usb support for asyncio encoded one of it's values in the wrong
field. It should have used si_value but instead used si_addr which is
not present in the _rt union member of struct siginfo.
The result is a POSIX and glibc incompatible encoding of fields in
struct siginfo with si_code of SI_A
Simplify field's initialization by directly assigning its final value
instead of initializing the variable to sero and then bitwise or-ing
it.

Changes since [v1]:
- Code changed to use __ffs()
- Added check for page_s
Xhci_handshake() implements the algorithm already captured by
readl_poll_timeout_atomic(). Convert the former to use the latter to
avoid repetition.

Stingray USB HS PHY has an issue, that USB High Speed device detected

This problem can be resolved with that port PHY reset

readl_poll_timeout() doesn't really work here as it might sleep.
