habanalabs: add basic Goya support

This patch adds a basic support for the Goya device. The code initializes
the device's PCI controller and PCI bars. It also initializes various S/W
structures and adds some basic helper functions.

+ * GOYA security scheme:
+ *
+ * 1. Host is protected by:
+ *        - Range registers (When MMU is enabled, DMA RR does NOT protect host)
+ *        - MMU
+ *
+ * 2. DRAM is protected by:
+ *        - Range registers (protect the first 512MB)
+ *        - MMU (isolation between users)
+ *
+ * 3. Configuration is protected by:
+ *        - Range registers
+ *        - Protection bits
+ *
+ * When MMU is disabled:
+ *
+ * QMAN DMA: PQ, CQ, CP, DMA are secured.
+ * PQ, CB and the data are on the host.
+ *
+ * QMAN TPC/MME:
+ * PQ, CQ and CP are not secured.
+ * PQ, CB and the data are on the SRAM/DRAM.
+ *
+ * Since QMAN DMA is secured, KMD is parsing the DMA CB:
+ *     - KMD checks DMA pointer
+ *     - WREG, MSG_PROT are not allowed.
+ *     - MSG_LONG/SHORT are allowed.
+ *
+ * A read/write transaction by the QMAN to a protected area will succeed if
+ * and only if the QMAN's CP is secured and MSG_PROT is used
+ *
+ *
+ * When MMU is enabled:
+ *
+ * QMAN DMA: PQ, CQ and CP are secured.
+ * MMU is set to bypass on the Secure props register of the QMAN.
+ * The reasons we don't enable MMU for PQ, CQ and CP are:
+ *     - PQ entry is in kernel address space and KMD doesn't map it.
+ *     - CP writes to MSIX register and to kernel address space (completion
+ *       queue).
+ *
+ * DMA is not secured but because CP is secured, KMD still needs to parse the
+ * CB, but doesn't need to check the DMA addresses.
+ *
+ * For QMAN DMA 0, DMA is also secured because only KMD uses this DMA and KMD
+ * doesn't map memory in MMU.
+ *
+ * QMAN TPC/MME: PQ, CQ and CP aren't secured (no change from MMU disabled mode)
+ *
+ * DMA RR does NOT protect host because DMA is not secured
