commit dbe7dc6b9b28f5b012b0bedc372aa0c52521f3e4 upstream.
Certain Micron eMMC v4.5 cards might get broken when HPI feature is used
and hence this patch disables the HPI feature for such buggy cards.
In U-Boot, these cards are reported as

Revision: 19 (0x13)

Tran Speed: 52000000
Rd Block Len: 512
MMC version 4.5
High Capacity: Yes
Capacity: 29.1 GiB
Boot Partition Size: 16 MiB
Bus Width: 8-bit
According to JEDEC JEP106 manufacturer 0xFE is Numonyx, which was bought by
Micron.
