  Some resource limits on IPA v3.5.1 have their max values set to
255, this causes a few splats in ipa_reg_encode and prevents the
IPA from booting properly. The limits are all 6 bits wide so
adjust the max values to 63.

Fixes: 1c418c4a929c ("net: ipa: define resource group/type IPA register fields")

V1: https://lore.kernel.org/netdev/20221024165636.3979249-1-caleb.connolly@linaro.org/
Changes since v1:
 * Apply the correct fix for v3.1 which has the opposite issue where the masks
   are wrong rather than the values.
 * Split into two patches

Thanks Caleb, this looks good.

David et al, in case it isn't obvious, this is for net/master,
for back-port (only to 6.0.y).
