intel/bd82x6x: Fix a small mistake in DIR_ROUTE
The register is 16-bits wide. If the DIR_ROUTE call ordering was reversed the previous writes would get overwritten. See page 407ff on the Intel C216 datasheet, which says "Size: 16bits" with "Default: 3210h" for all DnnIR registers. This also makes sense given the register offsets: 3140h–3141h D31IR Device 31 Interrupt Route 3210h R/W [3142h would be D30IR] 3144h–3145h D29IR Device 29 Interrupt Route 3210h R/W 3146h–3147h D28IR Device 28 Interrupt Route 3210h R/W 3148h–3149h D27IR Device 27 Interrupt Route 3210h R/W 314Ch–314Dh D26IR Device 26 Interrupt Route 3210h R/W 3150h–3151h D25IR Device 25 Interrupt Route 3210h R/W [discontinuity in register addresses here] 315Ch–315Dh D22IR Device 22 Interrupt Route 3210h R/W [315Eh would be D21IR] 3160h–3161h D20IR Device 20 Interrupt Route 3210h R/W Change-Id: I970abbacbc2c59e86c1726171272b8779758e53e Signed-off-by: Tobias Diedrich <ranma+coreboot@tdiedrich.de> Reviewed-on: https://review.coreboot.org/22621 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Patrick Rudolph <siro@das-labor.org>
