Fixes: commit 0611c41934ab35ce84dea34ab291897ad3cbc7be
ARM: OMAP2+: gpmc: update gpmc_hwecc_bch_capable() for new platforms and ECC schemes
Though the commit log of above commit mentions AM43xx platforms, but code change
missed AM43xx. This patch adds AM43xx to list of those SoC which have built-in
ELM hardware engine, so that BCH ecc-schemes with hardware error-correction can
be enabled on AM43xx devices.
