All interconnect device tree nodes on sm8450 are 2-cells, however in
UFS node they are handled as 1-cells, fix it.

Bjorn, could you please this pick for the -rc kernel?

The change is obviously correct, but what difference does this change
make with the current implementation?

it makes interconnect paths probe correctly. All NoC have
#interconnec-cells = <2> now.

But there's no code in the UFS driver that calls of_icc_get(), so what
does this actually do? (Other than correcting the dtb for the day when
we add that support to the driver).

FWIW the change also has a runtime effect, it fixes a parsing of the board dtb,
otherwise a warning in the kernel log appears:

   OF: /soc@0/ufshc@1d84000: could not get #interconnect-cells for /clocks/sleep-clk

Why /clocks/sleep-clk is mentioned here at all??
Its phandle value is 0x26, which is equal to SLAVE_UFS_MEM_CFG from the array.
