mmc: block: skip trim for some kingston eMMCs
For some mass production of kingston eMMCs which adopt Phison's firmware will meet an unrecoverable data conrruption occasionally if performing trim due to a firmware bug confirmed by vendor. We found it on Intel-C3230RK platform. So we add fixup of broken trim for it. Signed-off-by: Shawn Lin <shawn.lin@rock-chips.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
