net: stmmac: make dma_cfg mixed/fixed burst boolean

Browse Source 
struct stmmac_dma_cfg mixed_burst/fixed_burst members are both boolean
in nature - of_property_read_bool() are used to read these from DT, and
they are only tested for non-zero values. Use bool to avoid unnecessary
padding in this structure.

Update dwmac-intel to initialise these using true rather than '1', and
remove the '0' initialisers as the struct is already zero initialised
on allocation.
