UBUNTU: [Config] Align configs with Unleashed defconfigs

The Unleashed defconfigs disable PM enable CPU freq with
usermode control'd cpu frequency scaling so ensure we are
following the recommended configuration. This also solves
some mysterious RCU stalling and some spurious flash drive
delays that cause boot and shutdown to become unreliable.

irqchip/sifive-plic: Fix broken irq_set_affinity() callback

It will always enable the interrupt after calling plic_set_affinity()
however it should set to it previous setting. Staying disabled or enabled.

This patch can also fix this pwm hang issue in Unleashed board.

i2c: ocores: fix polling mode workaround on FU540-C000 SoC

The FU540-C000 has a broken IRQ and support was added earlier
so that it will operate in polling mode, but seems to work only
in case interrupts property is missing from the i2c0 dt-node.
This should not be the case and the driver should handle polling
mode with the interrupt property present in i2c0 node of the
device tree.
So check if it's the FU540-C000 soc and enable polling mode master
xfers, as the IRQ for this chip is broken.

Fixes commit c45d4ba86731 ("i2c: ocores: add polling mode workaround
for Sifive FU540-C000 SoC")
