Subject: [PATCH 08/11] ARM: dts: qcom: sdx65-mtp: Increase the vmalloc size

Increase the size of vmalloc using the bootargs in sdx65
mtp board.
It is failing to alloacte the size needed for firmware and
giving the error logs due to actual vmalloc region lesser than requested.

cat /proc/meminfo shows the size of VmallocTotal as 245760 kB.

[ 10.980356] vmap allocation for size 268439552 failed: use vmalloc=<size> to increase size
[ 10.980505] qcom_q6v5_pas 4080000.remoteproc: unable to map memory region: 0x90800000+10000000
[ 10.988542] In adsp alloc memory: adsp_probe 482
[ 10.988592] remoteproc remoteproc0: releasing 4080000.remoteproc
[ 11.001598] qcom_q6v5_pas: probe of 4080000.remoteproc failed with error -16

Thus, increasing the size to 300000000 as modem is not the only one using vmalloc region.
