Although downstream supports HS400, there are overclocking warnings when
using mmc-hs400-1_8v:
mmc0: Card appears overclocked; req 200000000 Hz, actual 384000000 Hz
mmc0: Card appears overclocked; req 200000000 Hz, actual 384000000 Hz
mmc0: Card appears overclocked; req 200000000 Hz, actual 384000000 Hz
mmc0: Card appears overclocked; req 400000000 Hz, actual 768000000 Hz
mmc0: Card appears overclocked; req 400000000 Hz, actual 768000000 Hz
mmc0: new HS400 MMC card at address 0001
Using HS200 (i.e. mmc-hs200-1_8v or mmc-ddr-1_8v) would reduce them:
mmc0: Card appears overclocked; req 200000000 Hz, actual 384000000 Hz
mmc0: Card appears overclocked; req 200000000 Hz, actual 384000000 Hz
mmc0: new HS200 MMC card at address 0001
But as the problem is probably elsewhere (bullhead behaves the same),
keep mmc-hs400-1_8v.
Angler does not have SD card, thus sdhc2 kept disabled.

Changes v2->v3:
* update sdhc1 overclocking comment.
