arm64: dts: hikey: Fix eMMC corruption regression
This patch is a partial revert of commit abd7d0972a19 ("arm64: dts: hikey: Enable HS200 mode on eMMC") which has been causing eMMC corruption on my HiKey board. Symptoms usually looked like: mmc_host mmc0: Bus speed (slot 0) = 24800000Hz (slot req 400000Hz, actual 400000HZ div = 31) ... mmc_host mmc0: Bus speed (slot 0) = 148800000Hz (slot req 150000000Hz, actual 148800000HZ div = 0) mmc0: new HS200 MMC card at address 0001 ... dwmmc_k3 f723d000.dwmmc0: Unexpected command timeout, state 3 mmc_host mmc0: Bus speed (slot 0) = 24800000Hz (slot req 400000Hz, actual 400000HZ div = 31) mmc_host mmc0: Bus speed (slot 0) = 148800000Hz (slot req 150000000Hz, actual 148800000HZ div = 0) mmc_host mmc0: Bus speed (slot 0) = 24800000Hz (slot req 400000Hz, actual 400000HZ div = 31) mmc_host mmc0: Bus speed (slot 0) = 148800000Hz (slot req 150000000Hz, actual 148800000HZ div = 0) mmc_host mmc0: Bus speed (slot 0) = 24800000Hz (slot req 400000Hz, actual 400000HZ div = 31) mmc_host mmc0: Bus speed (slot 0) = 148800000Hz (slot req 150000000Hz, actual 148800000HZ div = 0) print_req_error: I/O error, dev mmcblk0, sector 8810504 Aborting journal on device mmcblk0p10-8. mmc_host mmc0: Bus speed (slot 0) = 24800000Hz (slot req 400000Hz, actual 400000HZ div = 31) mmc_host mmc0: Bus speed (slot 0) = 148800000Hz (slot req 150000000Hz, actual 148800000HZ div = 0) mmc_host mmc0: Bus speed (slot 0) = 24800000Hz (slot req 400000Hz, actual 400000HZ div = 31) mmc_host mmc0: Bus speed (slot 0) = 148800000Hz (slot req 150000000Hz, actual 148800000HZ div = 0) mmc_host mmc0: Bus speed (slot 0) = 24800000Hz (slot req 400000Hz, actual 400000HZ div = 31) mmc_host mmc0: Bus speed (slot 0) = 148800000Hz (slot req 150000000Hz, actual 148800000HZ div = 0) mmc_host mmc0: Bus speed (slot 0) = 24800000Hz (slot req 400000Hz, actual 400000HZ div = 31) mmc_host mmc0: Bus speed (slot 0) = 148800000Hz (slot req 150000000Hz, actual 148800000HZ div = 0) EXT4-fs error (device mmcblk0p10): ext4_journal_check_start:61: Detected aborted journal EXT4-fs (mmcblk0p10): Remounting filesystem read-only And quite often this would result in a disk that wouldn't properly boot even with older kernels. It seems the max-frequency property added by the above patch is causing the problem, so remove it.
