By default, edk2 allows 1000000μs for SD Card Readers and eMMC to
initialize which is excessive and causes a boot delay. This makes
the value configurable and uses a default of 1000μs which is sufficient
for the majority of readers. The value of 1000μs was hardcoded in
MrChromeBox's fork for around 2 years with no reported issues.
