[PATCH 1/4] Add a new member 'name' to structure irq_host.

[Zhang Wei <wei.zhang@freescale.com>]

This patch adds a new member 'name' for irq host's name to structure irq_host and modifies the definition of the function irq_alloc_host(). The assignment to the irq host's name is also added to irq_alloc_host().
