ARCv2: [plat-hsdk]: Save accl reg pair by default
This manifsted as strace segfaulting on HSDK because gcc was targetting the accumulator registers as GPRs, which kernek was not saving/restoring by default. Cc: stable@vger.kernel.org #4.14+ Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

Depending on the configuration, CPU can contain accumulator reg-pair
(also referred to as r58:r59). These can also be used by gcc as GPR so
