pru: Use unsigned constants for register classes

Fix the following warning:

  .../gcc/gcc/config/pru/pru.h:249:43: warning: narrowing conversion of ‘-1’ from ‘int’ to ‘unsigned int’ [-Wnarrowing]
    249 |     /* ALL_REGS       */ { ~0,~0, ~0, ~0, ~0}                   \

gcc/ChangeLog:

	* config/pru/pru.h (REG_CLASS_CONTENTS): Use unsigned integer
	constants.
