sparc, sparc64: use arch/sparc/include

The majority of this patch was created by the following script:

***
ASM=arch/sparc/include/asm
mkdir -p $ASM
git mv include/asm-sparc64/ftrace.h $ASM
git rm include/asm-sparc64/*
git mv include/asm-sparc/* $ASM
sed -ie 's/asm-sparc64/asm/g' $ASM/*
sed -ie 's/asm-sparc/asm/g' $ASM/*
***

The rest was an update of the top-level Makefile to use sparc
for header files when sparc64 is being build.
And a small fixlet to pick up the correct unistd.h from
sparc64 code.

+ * The driver supports 4 operations: open(), close(), ioctl(), read()
+ * The device name is /dev/envctrl.
+ * Below is sample usage:
+ *
+ *      fd = open("/dev/envtrl", O_RDONLY);
+ *      if (ioctl(fd, ENVCTRL_READ_SHUTDOWN_TEMPERATURE, 0) < 0)
+ *              printf("error\n");
+ *      ret = read(fd, buf, 10);
+ *      close(fd);
+ *
+ * Notice in the case of cpu voltage and temperature, the default is
+ * cpu0.  If we need to know the info of cpu1, cpu2, cpu3, we need to
+ * pass in cpu number in ioctl() last parameter.  For example, to
+ * get the voltage of cpu2:
+ *
+ *      ioctlbuf[0] = 2;
+ *      if (ioctl(fd, ENVCTRL_READ_CPU_VOLTAGE, ioctlbuf) < 0)
+ *              printf("error\n");
+ *      ret = read(fd, buf, 10);
+ *
+ * All the return values are in ascii.  So check read return value
+ * and do appropriate conversions in your application.
