drm/i915: Do not match JSL in ehl_combo_pll_div_frac_wa_needed()

Since commit 0c65dc062611 ("drm/i915/jsl: s/JSL/JASPERLAKE for
platform/subplatform defines"), boot freezes on a Jasper Lake tablet
(Librem 11), usually with graphical corruption on the eDP display,
but sometimes just a black screen.  This commit was included in 6.6 and
later.

That commit was intended to refactor EHL and JSL macros, but the change
to ehl_combo_pll_div_frac_wa_needed() started matching JSL incorrectly
when it was only intended to match EHL.

It replaced:
	return ((IS_PLATFORM(i915, INTEL_ELKHARTLAKE) &&
		 IS_JSL_EHL_DISPLAY_STEP(i915, STEP_B0, STEP_FOREVER)) ||
with:
	return (((IS_ELKHARTLAKE(i915) || IS_JASPERLAKE(i915)) &&
		 IS_DISPLAY_STEP(i915, STEP_B0, STEP_FOREVER)) ||

Remove IS_JASPERLAKE() to fix the regression.
