drm/i915: Add retries for LSPCON detection
We read the dp dual mode Adapter identifier to detect the
LSPCON device. It's been observed from the CI testing that in
few cases, this read can get delayed or fail. For such scenarios,
LSPCON vendors suggest to retry the read operation.
This patch adds retry in the probe function, while reading
LSPCON identifier.
