driver/fsl-mc: Add support of MC Flibs

Freescale's Layerscape Management Complex (MC) provide support various
objects like DPRC, DPNI, DPBP and DPIO.
Where:
	DPRC: Place holdes for other MC objectes like DPNI, DPBP, DPIO
	DPBP: Management of buffer pool
	DPIO: Used for used to QBMan portal
	DPNI: Represents standard network interface

These objects are used for DPAA ethernet drivers.

+ *
+ * Eg. to "d"ecode a 14-bit field out of a register (into a "uint16_t" type),
+ * where the field is located 3 bits "up" from the least-significant bit of the
+ * register (ie. the field location within the 32-bit register corresponds to a
+ * mask of 0x0001fff8), you would do;
+ *                uint16_t field = d32_uint16_t(3, 14, reg_value);
+ *
+ * Or to "e"ncode a 1-bit boolean value (input type is "int", zero is FALSE,
+ * non-zero is TRUE, so must convert all non-zero inputs to 1, hence the "!!"
+ * operator) into a register at bit location 0x00080000 (19 bits "in" from the
+ * LS bit), do;
+ *                reg_value |= e32_int(19, 1, !!field);
+ *
+ * If you wish to read-modify-write a register, such that you leave the 14-bit
+ * field as-is but have all other fields set to zero, then "i"solate the 14-bit
+ * value using;
+ *                reg_value = i32_uint16_t(3, 14, reg_value);
+ *
+ * Alternatively, you could "r"emove the 1-bit boolean field (setting it to
+ * zero) but leaving all other fields as-is;
+ *                reg_val = r32_int(19, 1, reg_value);
