hppa: use new CONFIG_HPPA_B160L option instead of CONFIG_DINO to build hppa machine

DINO refers to the GSC-PCI bridge device which will soon be handled separately,
however the QEMU HPPA machine is actually based upon the HPPA B160L as indicated
by the Linux kernel dmesg output when booted in qemu-system-hppa and the QEMU
MAINTAINERS file.

Update the machine configuration to use CONFIG_HPPA_B160L instead of CONFIG_DINO
and also update the machine description accordingly.
