payloads/tianocore: Increase default timeout for SD MMC init to 10ms
Firstly, change the unit of `μs` to `ms` so it's easier to read.
This patch changes the default amount of time allowed to initialise
SD Card Readers and eMMC drives from 1ms to 10ms. Having a timeout
too short will stop certain devices from booting, which was seen on
google/akemi; it throws an exception when attempting to boot from
the internal eMMC drive.
This new value is still lower than upstream edk2's value of 1s.
