clk: actions: owl-pll: cast delay to unsigned long for udelay()

The 'delay' field in struct owl_pll_hw is u8, but udelay() internally
compares its argument against MAX_UDELAY_MS * 1000 (2000). Since a u8
can never exceed 255, the compiler warns of a tautological comparison
that is always false:

  drivers/clk/actions/owl-pll.c:189:2: error: result of comparison of
  constant 2000 with expression of type 'u8' is always false

Cast the delay value to unsigned long to widen the type and silence the
W=1 warning without changing behavior.
