staging: mt7621-pci: avoid using clk_* operations
There is no clock driver for ralink mips and clk_enable
are no-ops for this architecture. This has been also tested
without using clocks and seems to work so avoid to use them
in this driver.
Fixes: ad9c87e129d1: "staging: mt7621-pci: parse and init
port data from device tree"
