Add a stub for __giveup_fpu() when CONFIG_PPC_FPU is
not selected, as done for CONFIG_SPE and CONFIG_ALTIVEC.
This allows to remove some #ifdef CONFIG_PPC_FPU.

introduce 'reset' method to allow device do serialized assert and
deassert operations in a single step, which needs a minimum delay
to be waited between assert and deassert.

The TI syscon reset controller provides a common reset management,
and is suitable for MTK SoCs. Add compatible 'mediatek,infra-reset',
which denotes to use ti reset-controller driver directly.

v4:
fix typos on v3 commit message.
v3:
1. revert v2 changes.
2. add 'reset-duration-us' property to declare a minimum delay,
which needs to be waited between assert and deassert.
3. add 'mediatek,infra-reset' to compatible.
v2 changes:

1. add
Introduce ti_syscon_reset() to integrate assert and deassert together.
If some modules need do serialized assert and deassert operations
to reset itself, reset_control_reset can be called for convenience.
Such as reset-qcom-aoss.c, it integrates assert and deassert together
by 'reset' method. MTK
add infracfg_rst node which is for MT8192 platform

Since commit bcf3440c6dd7 ("net: phy: micrel: add phy-mode support for the
KSZ9031 PHY") the networking is broken on the imx7d-zii-rmu2 board.
Fix it by switching to phy-mode = "rgmii-id".

The kci_test_encap_fou() test from kci_test_encap() in rtnetlink.sh
needs the fou module to work. Otherwise it will fail with:

We have a number of "uart.port->desc.lock vs desc.lock->uart.port"
lockdep reports coming from 8250 driver; this causes a bit of trouble
to people, so let's fix it.
The problem is reverse lock order in two different call paths:
chain #1:
serial8250_do_startup()
spin_lock_irqsave(>lock);
