mmc: sdhci: Fix voltage switch delay
I am seeing a boot regression on a couple boards and bisect is pointing
to the above commit.
Same thing here, getting a hard lock for our devices with the SDHCI
controller enabled, sometimes we are lucky to see the following:
[ 4.790367] mmc0: SDHCI controller on 84b0000.sdhci [84b0000.sdhci]
using ADMA 64-bit

Also confirmed that reverting that change ("mmc: sdhci: Fix voltage
switch delay") allows devices to boot properly.
Had not a chance to test the change when submitted for mainline despite
being copied, sorry about that.
Since that specific commit is also included in the other stable trees
(5.4, 5.10, 5.15 and 6.0) I will let you know whether the same issue is
present in those trees shortly thereafter.
