Various other helpers contain open-coded implementations of
hrtimer_cb_get_time(). This prevents refactoring the implementation.
Reuse the existing helper.
For this to work, move hrtimer_cb_get_time() a bit up in the file and also
make its argument 'const'.

AST2700 continues the multi-instance SCU interrupt controller model
introduced in the AST2600, with four independent interrupt domains (scu-ic0
to 3).
Unlike earlier generations which combine interrupt enable and status bits
into a single register, AST2700 separates these into distinct IER and ISR
registers. Support for this layout is implemented by using register offsets
and separate chained IRQ handlers.
The variant table is extended to cover AST2700 IC instances, enabling
shared initialization logic while preserving support for previous SoCs.

The SCU IC driver handles each AST2600 instance with separate
initialization functions and hardcoded register definitions, which is
inflexible and creates duplicated code.
Consolidate the implementation by introducing a variant-based structure,
selected via compatible string, and use a unified init path and MMIO access
via of_iomap(). This simplifies the code and prepares for upcoming SoCs
like AST2700, which require split register handling.

Add selftest for the IPv6 fragmentation regression which affected
several stable kernels.
Commit a18dfa9925 ("ipv6: save dontfrag in cork") was backported to
stable without some prerequisite commits. This caused a regression when
sending IPv6 UDP packets by preventing fragmentation and instead
returning -1 (EMSGSIZE).
Add selftest to check for this issue by attempting to send a packet
larger than the interface MTU. The packet will be fragmented on a
working kernel, with sendmsg(2) correctly returning the expected number
of bytes sent. When the regression is present, sendmsg returns -1 and
sets errno to EMSGSIZE.
