pwm: lpc18xx-sct: Reduce number of devm memory allocations
[ Upstream commit 20d9de9c4d6642bb40c935233697723b56573cbc ]
Each devm allocations has an overhead of 24 bytes to store the related
struct devres_node additionally to the fragmentation of the allocator.
So allocating 16 struct lpc18xx_pwm_data (which only hold a single int)
adds quite some overhead. Instead put the per-channel data into the
driver data struct and allocate it in one go.
