Initializes an HMatrix Master configuration structure to defaults.
Initializes a given HMatrix Master channel configuration structure to a set of known default values. This function should be called on all new instances of these configuration structures before being modified by the user application.
The default configuration is as follows:
| config | Configuration structure to initialize to default values |
References Assert, hmatrix_master_ch_conf::burst_type, and HMATRIX_BURST_FOUR_BEAT.
