gpu: host1x: Add Tegra186 support
Add support for the implementation of Host1x present on the Tegra186. The register space has been shuffled around a little bit, requiring addition of some chip-specific code sections. Tegra186 also adds several new features, most importantly the hypervisor, but those are not yet supported with this commit.

+ * Function naming determines intended use:

+ * <x>_r(void) : Returns the offset for register <x>.
+ *
+ * <x>_w(void) : Returns the word offset for word (4 byte) element <x>.
+ *
+ * <x>_<y>_s(void) : Returns size of field <y> of register <x> in bits.
+ *
+ * <x>_<y>_f(u32 v) : Returns a value based on 'v' which has been shifted
+ * and masked to place it at field <y> of register <x>. This value
+ * can be |'d with others to produce a full register value for
+ * register <x>.
+ *
+ * <x>_<y>_m(void) : Returns a mask for field <y> of register <x>. This
+ * value can be ~'d and then &'d to clear the value of field <y> for
+ * register <x>.
+ *
+ * <x>_<y>_<z>_f(void) : Returns the constant value <z> after being shifted
+ * to place it at field <y> of register <x>. This value can be |'d
+ * with others to produce a full register value for <x>.
+ *
+ * <x>_<y>_v(u32 r) : Returns the value of field <y> from a full register
+ * <x> value 'r' after being shifted to place its LSB at bit 0.
+ * This value is suitable for direct comparison with other unshifted
+ * values appropriate for use in field <y> of register <x>.
+ *
+ * <x>_<y>_<z>_v(void) : Returns the constant value for <z> defined for
