mmc: core: Allow dynamical updates of the number of requests for hsq
To allow dynamical updates of the current number of used in-flight
requests, let's move away from using a hard-coded value to a use a
corresponding variable in the struct mmc_host.
This can be valuable when optimizing for certain I/O request sequences, as
shown by subsequent changes.
