[PATCH] clk: actions: owl-pll: cast delay to unsigned long for uelay()

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
warning without changing behavior.
